+ *
+ * Francois-Rene Rideau <fare@tunes.org> 19970707
+ *    gathered all the good ideas from all asm-foo/byteorder.h into one file,
+ *    cleaned them up.
+ *    I hope it is compliant with non-GCC compilers.
+ *    I decided to put __BYTEORDER_HAS_U64__ in byteorder.h,
+ *    because I wasn't sure it would be ok to put it in types.h
+ *    Upgraded it to 2.1.43
+ * Francois-Rene Rideau <fare@tunes.org> 19971012
+ *    Upgraded it to 2.1.57
+ *    to please Linus T., replaced huge #ifdef's between little/big endian
+ *    by nestedly #include'd files.
+ * Francois-Rene Rideau <fare@tunes.org> 19971205
+ *    Made it to 2.1.71; now a facelift:
+ *    Put files under include/linux/byteorder/
+ *    Split swab from generic support.
+ *
+ * TODO:
+ *   = Regular kernel maintainers could also replace all these manual
+ *    byteswap macros that remain, disseminated among drivers,
+ *    after some grep or the sources...
+ *   = Linus might want to rename all these macros and files to fit his taste,
+ *    to fit his personal naming scheme.
+ *   = it seems that a few drivers would also appreciate
+ *    nybble swapping support...
+ *   = every architecture could add their byteswap macro in asm/byteorder.h
+ *    see how some architectures already do (i386, alpha, ppc, etc)
+ *   = cpu_to_beXX and beXX_to_cpu might some day need to be well
+ *    distinguished throughout the kernel. This is not the case currently,
+ *    since little endian, big endian, and pdp endian machines needn't it.
+ *    But this might be the case for, say, a port of Linux to 20/21 bit
+ *    architectures (and F21 Linux addict around?).
+ */

+ *      ntohs(__u16 x)
+ *      htonl(__u32 x)
+ *      htons(__u16 x)
+ * It seems that some programs (which? where? or perhaps a standard? POSIX?)
+ * might like the above to be functions, not macros (why?).
+ * if that's true, then detect them, and take measures.
+ * Anyway, the measure is: define only ___ntohl as a macro instead,
+ * and in a separate file, have
+ * unsigned long inline ntohl(x){return ___ntohl(x);}
+ *
+ * The same for constant arguments
+ *      __constant_ntohl(__u32 x)
+ *      __constant_ntohs(__u16 x)
+ *      __constant_htonl(__u32 x)
+ *      __constant_htons(__u16 x)
+ *
+ * Conversion of XX-bit integers (16- 32- or 64-)
+ * between native CPU format and little/big endian format
+ * 64-bit stuff only defined for proper architectures
+ *      cpu_to_[bl]eXX(__uXX x)
+ *      [bl]eXX_to_cpu(__uXX x)

+ *      cpu_to_[bl]eXXp(__uXX x)
+ *      [bl]eXX_to_cpup(__uXX x)

+/*******************************************************
+ * As of Linux 2.1.x, all Linux CD-ROM application programs will use this 
+ * (and only this) include file.  It is my hope to provide Linux with
+ * a uniform interface between software accessing CD-ROMs and the various 
+ * device drivers that actually talk to the drives.  There may still be
+ * 23 different kinds of strange CD-ROM drives, but at least there will 
+ * now be one, and only one, Linux CD-ROM interface.
+ *
+ * Additionally, as of Linux 2.1.x, all Linux application programs 
+ * should use the O_NONBLOCK option when opening a CD-ROM device 
+ * for subsequent ioctl commands.  This allows for neat system errors 
+ * like "No medium found" or "Wrong medium type" upon attempting to 
+ * mount or play an empty slot, mount an audio disc, or play a data disc.
+ * Generally, changing an application program to support O_NONBLOCK
+ * is as easy as the following:
+ *       -    drive = open("/dev/cdrom", O_RDONLY);
+ *       +    drive = open("/dev/cdrom", O_RDONLY | O_NONBLOCK);
+ * It is worth the small change.
+ *
+ *  Patches for many common CD programs (provided by David A. van Leeuwen)
+ *  can be found at:  ftp://ftp.gwdg.de/pub/linux/cdrom/drivers/cm206/
+ *

+/* When a driver supports a certain function, but the cdrom drive we are

+ * accomplish this.  Maybe someday we will get a more targeted error code, 
+ * but this will do for now... */

+ *     cpu_online_map   - has bit 'cpu' set iff cpu available to scheduler
+ *  #endif
+ *
+ *  In either case, NR_CPUS is fixed at compile time, as the static
+ *  size of these bitmaps.  The cpu_possible_map is fixed at boot
+ *  time, as the set of CPU id's that it is possible might ever
+ *  be plugged in at anytime during the life of that system boot.
+ *  The cpu_present_map is dynamic(*), representing which CPUs
+ *  are currently plugged in.  And cpu_online_map is the dynamic
+ *  subset of cpu_present_map, indicating those CPUs available
+ *  for scheduling.
+ *
+ *  If HOTPLUG is enabled, then cpu_possible_map is forced to have
+ *  all NR_CPUS bits set, otherwise it is just the set of CPUs that
+ *  ACPI reports present at boot.
+ *
+ *  If HOTPLUG is enabled, then cpu_present_map varies dynamically,
+ *  depending on what ACPI reports as currently plugged in, otherwise
+ *  cpu_present_map is just a copy of cpu_possible_map.
+ *
+ *  (*) Well, cpu_present_map is dynamic in the hotplug case.  If not
+ *      hotplug, it's a copy of cpu_possible_map, hence fixed at boot.
+ *
+ * Subtleties:
+ * 1) UP arch's (NR_CPUS == 1, CONFIG_SMP not defined) hardcode
+ *    assumption that their single CPU is online.  The UP
+ *    cpu_{online,possible,present}_maps are placebos.  Changing them
+ *    will have no useful affect on the following num_*_cpus()
+ *    and cpu_*() macros in the UP case.  This ugliness is a UP
+ *    optimization - don't waste any instructions or memory references
+ *    asking if you're online or how many CPUs there are if there is
+ *    only one CPU.
+ * 2) Most SMP arch's #define some of these maps to be some
+ *    other map specific to that arch.  Therefore, the following
+ *    must be #define macros, not inlines.  To see why, examine
+ *    the assembly code produced by the following.  Note that
+ *    set1() writes phys_x_map, but set2() writes x_map:
+ *        int x_map, phys_x_map;
+ *        #define set1(a) x_map = a
+ *        inline void set2(int a) { x_map = a; }
+ *        #define x_map phys_x_map

+ * A traditional ioctl interface for the device mapper.

+ * 'active' table which is the one currently used by io passing
+ * through the device, and an 'inactive' one which is a table
+ * that is being prepared as a replacement for the 'active' one.
+ *
+ * DM_VERSION:
+ * Just get the version information for the ioctl interface.
+ *
+ * DM_REMOVE_ALL:
+ * Remove all dm devices, destroy all tables.  Only really used
+ * for debug.
+ *
+ * DM_LIST_DEVICES:
+ * Get a list of all the dm device names.
+ *
+ * DM_DEV_CREATE:
+ * Create a new device, neither the 'active' or 'inactive' table
+ * slots will be filled.  The device will be in suspended state
+ * after creation, however any io to the device will get errored
+ * since it will be out-of-bounds.
+ *
+ * DM_DEV_REMOVE:
+ * Remove a device, destroy any tables.
+ *
+ * DM_DEV_RENAME:
+ * Rename a device.
+ *
+ * DM_SUSPEND:
+ * This performs both suspend and resume, depending which flag is
+ * passed in.
+ * Suspend: This command will not return until all pending io to
+ * the device has completed.  Further io will be deferred until
+ * the device is resumed.
+ * Resume: It is no longer an error to issue this command on an
+ * unsuspended device.  If a table is present in the 'inactive'
+ * slot, it will be moved to the active slot, then the old table
+ * from the active slot will be _destroyed_.  Finally the device
+ * is resumed.
+ *
+ * DM_DEV_STATUS:
+ * Retrieves the status for the table in the 'active' slot.
+ *
+ * DM_DEV_WAIT:
+ * Wait for a significant event to occur to the device.  This
+ * could either be caused by an event triggered by one of the
+ * targets of the table in the 'active' slot, or a table change.
+ *
+ * DM_TABLE_LOAD:
+ * Load a table into the 'inactive' slot for the device.  The
+ * device does _not_ need to be suspended prior to this command.
+ *
+ * DM_TABLE_CLEAR:
+ * Destroy any table in the 'inactive' slot (ie. abort).
+ *
+ * DM_TABLE_DEPS:
+ * Return a set of device dependencies for the 'active' table.
+ *
+ * DM_TABLE_STATUS:
+ * Return the targets status for the 'active' table.
+ *
+ * DM_TARGET_MSG:
+ * Pass a message string to the target at a specific offset of a device.

+ * boot devices.
+ * In arch/{i386,x86_64}/kernel/setup.c, this information is
+ * transferred into the edd structure, and in drivers/firmware/edd.c, that
+ * information is used to identify BIOS boot disk.  The code in setup.S

+ * encode_fh:      encode a file handle fragment from a dentry
+ * get_name:       find the name for a given inode in a given directory

+ * get_dentry:     find a dentry for the inode given a file handle sub-fragment
+ *
+ * Description:
+ *    The export_operations structure provides a means for nfsd to communicate
+ *    with a particular exported file system  - particularly enabling nfsd and
+ *    the filesystem to co-operate when dealing with file handles.
+ *
+ *    export_operations contains two basic operation for dealing with file handles,
+ *    decode_fh() and encode_fh(), and allows for some other operations to be defined
+ *    which standard helper routines use to get specific information from the
+ *    filesystem.
+ *
+ *    nfsd encodes information use to determine which filesystem a filehandle
+ *    applies to in the initial part of the file handle.  The remainder, termed a
+ *    file handle fragment, is controlled completely by the filesystem.
+ *    The standard helper routines assume that this fragment will contain one or two
+ *    sub-fragments, one which identifies the file, and one which may be used to
+ *    identify the (a) directory containing the file.
+ *
+ *    In some situations, nfsd needs to get a dentry which is connected into a
+ *    specific part of the file tree.  To allow for this, it passes the function
+ *    acceptable() together with a @context which can be used to see if the dentry
+ *    is acceptable.  As there can be multiple dentrys for a given file, the filesystem
+ *    should check each one for acceptability before looking for the next.  As soon
+ *    as an acceptable one is found, it should be returned.
+ *
+ * decode_fh:
+ *    @decode_fh is given a &struct super_block (@sb), a file handle fragment (@fh, @fh_len)
+ *    and an acceptability testing function (@acceptable, @context).  It should return
+ *    a &struct dentry which refers to the same file that the file handle fragment refers
+ *    to,  and which passes the acceptability test.  If it cannot, it should return
+ *    a %NULL pointer if the file was found but no acceptable &dentries were available, or
+ *    a %ERR_PTR error code indicating why it couldn't be found (e.g. %ENOENT or %ENOMEM).
+ *
+ * encode_fh:
+ *    @encode_fh should store in the file handle fragment @fh (using at most @max_len bytes)
+ *    information that can be used by @decode_fh to recover the file refered to by the
+ *    &struct dentry @de.  If the @connectable flag is set, the encode_fh() should store
+ *    sufficient information so that a good attempt can be made to find not only
+ *    the file but also it's place in the filesystem.   This typically means storing
+ *    a reference to de->d_parent in the filehandle fragment.
+ *    encode_fh() should return the number of bytes stored or a negative error code
+ *    such as %-ENOSPC
+ *
+ * get_name:
+ *    @get_name should find a name for the given @child in the given @parent directory.
+ *    The name should be stored in the @name (with the understanding that it is already
+ *    pointing to a a %NAME_MAX+1 sized buffer.   get_name() should return %0 on success,
+ *    a negative error code or error.
+ *    @get_name will be called without @parent->i_sem held.
+ *
+ * get_parent:
+ *    @get_parent should find the parent directory for the given @child which is also
+ *    a directory.  In the event that it cannot be found, or storage space cannot be
+ *    allocated, a %ERR_PTR should be returned.
+ *
+ * get_dentry:
+ *    Given a &super_block (@sb) and a pointer to a file-system specific inode identifier,
+ *    possibly an inode number, (@inump) get_dentry() should find the identified inode and
+ *    return a dentry for that inode.
+ *    Any suitable dentry can be returned including, if necessary, a new dentry created
+ *    with d_alloc_root.  The caller can then find any other extant dentrys by following the
+ *    d_alias links.  If a new dentry was created using d_alloc_root, DCACHE_NFSD_DISCONNECTED
+ *    should be set, and the dentry should be d_rehash()ed.
+ *
+ *    If the inode cannot be found, either a %NULL pointer or an %ERR_PTR code can be returned.
+ *    The @inump will be whatever was passed to nfsd_find_fh_dentry() in either the
+ *    @obj or @parent parameters.
+ *
+ * Locking rules:
+ *  get_parent is called with child->d_inode->i_sem down
+ *  get_name is not (which is possibly inconsistent)

+ * For initialized data:
+ * You should insert __initdata between the variable name and equal

+ * This file describes an interface to an IPMI driver.  You have to
+ * have a fairly good understanding of IPMI to use this, so go read
+ * the specs first before actually trying to do anything.
+ *
+ * With that said, this driver provides a multi-user interface to the
+ * IPMI driver, and it allows multiple IPMI physical interfaces below
+ * the driver.  The physical interfaces bind as a lower layer on the
+ * driver.  They appear as interfaces to the application using this
+ * interface.
+ *
+ * Multi-user means that multiple applications may use the driver,
+ * send commands, receive responses, etc.  The driver keeps track of
+ * commands the user sends and tracks the responses.  The responses
+ * will go back to the application that send the command.  If the
+ * response doesn't come back in time, the driver will return a
+ * timeout error response to the application.  Asynchronous events
+ * from the BMC event queue will go to all users bound to the driver.
+ * The incoming event queue in the BMC will automatically be flushed
+ * if it becomes full and it is queried once a second to see if
+ * anything is in it.  Incoming commands to the driver will get
+ * delivered as commands.
+ *
+ * This driver provides two main interfaces: one for in-kernel
+ * applications and another for userland applications.  The
+ * capabilities are basically the same for both interface, although
+ * the interfaces are somewhat different.  The stuff in the
+ * #ifdef KERNEL below is the in-kernel interface.  The userland
+ * interface is defined later in the file.  */

+*
+* This group of IOCTLs deal with the record settings of the DSP
+*
+* The IXJCTL_REC_DEPTH command sets the internal buffer depth of the DSP.
+* Setting a lower depth reduces latency, but increases the demand of the
+* application to service the driver without frame loss.  The DSP has 480
+* bytes of physical buffer memory for the record channel so the true
+* maximum limit is determined by how many frames will fit in the buffer.
+*
+* 1 uncompressed (480 byte) 16-bit linear frame.
+* 2 uncompressed (240 byte) 8-bit A-law/mu-law frames.
+* 15 TrueSpeech 8.5 frames.
+* 20 TrueSpeech 6.3,5.3,4.8 or 4.1 frames.
+*
+* The default in the driver is currently set to 2 frames.
+*
+* The IXJCTL_REC_VOLUME and IXJCTL_PLAY_VOLUME commands both use a Q8
+* number as a parameter, 0x100 scales the signal by 1.0, 0x200 scales the
+* signal by 2.0, 0x80 scales the signal by 0.5.  No protection is given
+* against over-scaling, if the multiplication factor times the input
+* signal exceeds 16 bits, overflow distortion will occur.  The default
+* setting is 0x100 (1.0).
+*
+* The IXJCTL_REC_LEVEL returns the average signal level (not r.m.s.) on
+* the most recently recorded frame as a 16 bit value.

+*
+* This IOCTL allows you to reassign values in the tone index table.  The
+* tone table has 32 entries (0 - 31), but the driver only allows entries
+* 13 - 27 to be modified, entry 0 is reserved for silence and 1 - 12 are
+* the standard DTMF digits and 28 - 31 are the DTMF tones for A, B, C & D.
+* The positions used internally for Call Progress Tones are as follows:
+*    Dial Tone   - 25
+*    Ring Back   - 26
+*    Busy Signal - 27
+*
+* The freq values are calculated as:
+* freq = cos(2 * PI * frequency / 8000)
+*
+* The most commonly needed values are already calculated and listed in the
+* enum IXJ_TONE_FREQ.  Each tone index can have two frequencies with
+* different gains, if you are only using a single frequency set the unused
+* one to 0.
+*
+* The gain values range from 0 to 15 indicating +6dB to -24dB in 2dB
+* increments.

+* IXJ_CADENCE_ELEMENT structures that sequentially define the states of
+* the tone sequence.  The tone_on_time and tone_off time are in
+* 250 microsecond intervals.  A pointer to this array is passed to the
+* driver as the ce element of an IXJ_CADENCE structure.  The elements_used
+* must be set to the number of IXJ_CADENCE_ELEMENTS in the array.  The
+* termination variable defines what to do at the end of a cadence, the
+* options are to play the cadence once and stop, to repeat the last
+* element of the cadence indefinitely, or to repeat the entire cadence
+* indefinitely.  The ce variable is a pointer to the array of IXJ_TONE
+* structures.  If the freq0 variable is non-zero, the tone table contents
+* for the tone_index are updated to the frequencies and gains defined.  It
+* should be noted that DTMF tones cannot be reassigned, so if DTMF tone
+* table indexs are used in a cadence the frequency and gain variables will
+* be ignored.
+*
+* If the array elements contain frequency parameters the driver will
+* initialize the needed tone table elements and begin playing the tone,
+* there is no preset limit on the number of elements in the cadence.  If
+* there is more than one frequency used in the cadence, sequential elements
+* of different frequencies MUST use different tone table indexes.  Only one
+* cadence can be played at a time.  It is possible to build complex
+* cadences with multiple frequencies using 2 tone table indexes by

+ * NSEC_JIFFIE_SC.  Note that these defines contain nothing but
+ * constants and so are computed at compile time.  SHIFT_HZ (computed in
+ * timex.h) adjusts the scaling for different HZ values.
+
+ * Scaled math???  What is that?
+ *
+ * Scaled math is a way to do integer math on values that would,
+ * otherwise, either overflow, underflow, or cause undesired div
+ * instructions to appear in the execution path.  In short, we "scale"
+ * up the operands so they take more bits (more precision, less
+ * underflow), do the desired operation and then "scale" the result back
+ * by the same amount.  If we do the scaling by shifting we avoid the
+ * costly mpy and the dastardly div instructions.
+
+ * Suppose, for example, we want to convert from seconds to jiffies
+ * where jiffies is defined in nanoseconds as NSEC_PER_JIFFIE.  The
+ * simple math is: jiff = (sec * NSEC_PER_SEC) / NSEC_PER_JIFFIE; We
+ * observe that (NSEC_PER_SEC / NSEC_PER_JIFFIE) is a constant which we
+ * might calculate at compile time, however, the result will only have
+ * about 3-4 bits of precision (less for smaller values of HZ).
+ *
+ * So, we scale as follows:
+ * jiff = (sec) * (NSEC_PER_SEC / NSEC_PER_JIFFIE);
+ * jiff = ((sec) * ((NSEC_PER_SEC * SCALE)/ NSEC_PER_JIFFIE)) / SCALE;
+ * Then we make SCALE a power of two so:
+ * jiff = ((sec) * ((NSEC_PER_SEC << SCALE)/ NSEC_PER_JIFFIE)) >> SCALE;
+ * Now we define:
+ * #define SEC_CONV = ((NSEC_PER_SEC << SCALE)/ NSEC_PER_JIFFIE))
+ * jiff = (sec * SEC_CONV) >> SCALE;
+ *
+ * Often the math we use will expand beyond 32-bits so we tell C how to
+ * do this and pass the 64-bit result of the mpy through the ">> SCALE"
+ * which should take the result back to 32-bits.  We want this expansion
+ * to capture as much precision as possible.  At the same time we don't
+ * want to overflow so we pick the SCALE to avoid this.  In this file,
+ * that means using a different scale for each range of HZ values (as
+ * defined in timex.h).
+ *
+ * For those who want to know, gcc will give a 64-bit result from a "*"
+ * operator if the result is a long long AND at least one of the
+ * operands is cast to long long (usually just prior to the "*" so as
+ * not to confuse it into thinking it really has a 64-bit operand,
+ * which, buy the way, it can do, but it take more code and at least 2
+ * mpys).
+
+ * We also need to be aware that one second in nanoseconds is only a
+ * couple of bits away from overflowing a 32-bit word, so we MUST use
+ * 64-bits to get the full range time in nanoseconds.
+
+ */
+
+/*
+ * Here are the scales we will use.  One for seconds, nanoseconds and
+ * microseconds.
+ *
+ * Within the limits of cpp we do a rough cut at the SEC_JIFFIE_SC and
+ * check if the sign bit is set.  If not, we bump the shift count by 1.

+ * mapping->clean_pages, mapping->dirty_pages and mapping->locked_pages;
+ * using the page->list list_head. These fields are also used for

+ *
+ * There is also a per-mapping radix tree mapping index to the page
+ * in memory if present. The tree is rooted at mapping->root.  
+ *
+ * All process pages can do I/O:

+ * @idVendor: USB vendor ID for a device; numbers are assigned

+ * @idProduct: Vendor-assigned product ID.
+ * @bcdDevice_lo: Low end of range of vendor-assigned product version numbers.
+ *      This is also used to identify individual product versions, for
+ *      a range consisting of a single device.
+ * @bcdDevice_hi: High end of version number range.  The range of product
+ *      versions is inclusive.
+ * @bDeviceClass: Class of device; numbers are assigned
+ *      by the USB forum.  Products may choose to implement classes,

+ * @bInterfaceClass: Class of interface; numbers are assigned

+ * @bInterfaceSubClass: Subclass of interface; associated with bInterfaceClass.

+ *
+ * In most cases, drivers will create a table of device IDs by using

+ * and provide it to the USB core through their usb_driver structure.
+ *
+ * See the usb_match_id() function for information about how matches are
+ * performed.  Briefly, you will normally use one of several macros to help
+ * construct these entries.  Each entry you provide will either identify
+ * one or more specific products, or will identify a class of products
+ * which have agreed to behave the same.  You should put the more specific
+ * matches towards the beginning of your table, so that driver_info can
+ * record quirks of specific products.

+ *  Changelog:
+ *   01-31-2000 DMW     Created
+ *   09-18-2000 SJH     Moved structure out of the Disk-On-Chip drivers
+ *                      so it can be used by other NAND flash device
+ *                      drivers. I also changed the copyright since none

+ *                      bat later if I did something naughty.
+ *   10-11-2000 SJH     Added private NAND flash structure for driver
+ *   10-24-2000 SJH     Added prototype for 'nand_scan' function
+ *   10-29-2001 TG      changed nand_chip structure to support 
+ *                      hardwarespecific function for accessing control lines

+ *                      command delay times for different chips
+ *   04-28-2002 TG      OOB config defines moved from nand.c to avoid duplicate
+ *                      defines in jffs2/wbuf.c
+ *   08-07-2002 TG      forced bad block location to byte 5 of OOB, even if
+ *                      CONFIG_MTD_NAND_ECC_JFFS2 is not set
+ *   08-10-2002 TG      extensions to nand_chip structure to support HW-ECC
+ *
+ *   08-29-2002 tglx    nand_chip structure: data_poi for selecting 
+ *                      internal / fs-driver buffer
+ *                      support for 6byte/512byte hardware ECC

+ * (in `cmp' array). This is quick as it requires only two elementary
+ * number comparisons in worst case. Further, we take advantage of

+ * This is the new flexible, extensible style NFSv2/v3 file handle.
+ * by Neil Brown <neilb@cse.unsw.edu.au> - March 2000
+ *
+ * The file handle is seens as a list of 4byte words.
+ * The first word contains a version number (1) and four descriptor bytes
+ * that tell how the remaining 3 variable length fields should be handled.
+ * These three bytes are auth_type, fsid_type and fileid_type.
+ *
+ * All 4byte values are in host-byte-order.
+ *
+ * The auth_type field specifies how the filehandle can be authenticated
+ * This might allow a file to be confirmed to be in a writable part of a
+ * filetree without checking the path from it upto the root.
+ * Current values:
+ *     0  - No authentication.  fb_auth is 0 bytes long
+ * Possible future values:
+ *     1  - 4 bytes taken from MD5 hash of the remainer of the file handle
+ *          prefixed by a secret and with the important export flags.
+ *
+ * The fsid_type identifies how the filesystem (or export point) is
+ *    encoded.
+ *  Current values:
+ *     0  - 4 byte device id (ms-2-bytes major, ls-2-bytes minor), 4byte inode number
+ *        NOTE: we cannot use the kdev_t device id value, because kdev_t.h
+ *              says we mustn't.  We must break it up and reassemble.
+ *     1  - 4 byte user specified identifier
+ *     2  - 4 byte major, 4 byte minor, 4 byte inode number - DEPRECATED
+ *     3  - 4 byte device id, encoded for user-space, 4 byte inode number
+ *
+ * The fileid_type identified how the file within the filesystem is encoded.
+ * This is (will be) passed to, and set by, the underlying filesystem if it supports
+ * filehandle operations.  The filesystem must not use the value '0' or '0xff' and may
+ * only use the values 1 and 2 as defined below:
+ *  Current values:
+ *    0   - The root, or export point, of the filesystem.  fb_fileid is 0 bytes.
+ *    1   - 32bit inode number, 32 bit generation number.
+ *    2   - 32bit inode number, 32 bit generation number, 32 bit parent directory inode number.

+ * PG_error is set to indicate that an I/O error occurred on this page.

+ * guarantees that this bit is cleared for a page when it first is entered into
+ * the page cache.

+ * PG_highmem pages are not permanently mapped into the kernel virtual address

+                       Under the terms of the GNU General Public License
+
+
+        pg.h defines the user interface to the generic ATAPI packet
+        command driver for parallel port ATAPI devices (pg). The
+        driver is loosely modelled after the generic SCSI driver, sg,
+        although the actual interface is different.
+
+        The pg driver provides a simple character device interface for
+        sending ATAPI commands to a device.  With the exception of the
+        ATAPI reset operation, all operations are performed by a pair
+        of read and write operations to the appropriate /dev/pgN device.
+        A write operation delivers a command and any outbound data in
+        a single buffer.  Normally, the write will succeed unless the
+        device is offline or malfunctioning, or there is already another
+        command pending.  If the write succeeds, it should be followed
+        immediately by a read operation, to obtain any returned data and
+        status information.  A read will fail if there is no operation
+        in progress.
+
+        As a special case, the device can be reset with a write operation,
+        and in this case, no following read is expected, or permitted.
+
+        There are no ioctl() operations.  Any single operation
+        may transfer at most PG_MAX_DATA bytes.  Note that the driver must
+        copy the data through an internal buffer.  In keeping with all
+        current ATAPI devices, command packets are assumed to be exactly
+        12 bytes in length.
+
+        To permit future changes to this interface, the headers in the
+        read and write buffers contain a single character "magic" flag.
+        Currently this flag must be the character "P".

+/*
+ *
+ * Each stripe contains one buffer per disc.  Each buffer can be in
+ * one of a number of states stored in "flags".  Changes between
+ * these states happen *almost* exclusively under a per-stripe
+ * spinlock.  Some very specific changes can happen in bi_end_io, and
+ * these are not protected by the spin lock.
+ *
+ * The flag bits that are used to represent these states are:
+ *   R5_UPTODATE and R5_LOCKED
+ *
+ * State Empty == !UPTODATE, !LOCK
+ *        We have no data, and there is no active request
+ * State Want == !UPTODATE, LOCK
+ *        A read request is being submitted for this block
+ * State Dirty == UPTODATE, LOCK
+ *        Some new data is in this buffer, and it is being written out
+ * State Clean == UPTODATE, !LOCK
+ *        We have valid data which is the same as on disc
+ *
+ * The possible state transitions are:
+ *
+ *  Empty -> Want   - on read or write to get old data for  parity calc
+ *  Empty -> Dirty  - on compute_parity to satisfy write/sync request.(RECONSTRUCT_WRITE)
+ *  Empty -> Clean  - on compute_block when computing a block for failed drive
+ *  Want  -> Empty  - on failed read
+ *  Want  -> Clean  - on successful completion of read request
+ *  Dirty -> Clean  - on successful completion of write request
+ *  Dirty -> Clean  - on failed write
+ *  Clean -> Dirty  - on compute_parity to satisfy write/sync (RECONSTRUCT or RMW)
+ *
+ * The Want->Empty, Want->Clean, Dirty->Clean, transitions
+ * all happen in b_end_io at interrupt time.
+ * Each sets the Uptodate bit before releasing the Lock bit.
+ * This leaves one multi-stage transition:
+ *    Want->Dirty->Clean
+ * This is safe because thinking that a Clean buffer is actually dirty
+ * will at worst delay some action, and the stripe will be scheduled
+ * for attention after the transition is complete.
+ *
+ * There is one possibility that is not covered by these states.  That
+ * is if one drive has failed and there is a spare being rebuilt.  We
+ * can't distinguish between a clean block that has been generated
+ * from parity calculations, and a clean block that has been
+ * successfully written to the spare ( or to parity when resyncing).
+ * To distingush these states we have a stripe bit STRIPE_INSYNC that
+ * is set whenever a write is scheduled to the spare, or to the parity
+ * disc if there is no spare.  A sync request clears this bit, and
+ * when we find it set with no buffers locked, we know the sync is
+ * complete.
+ *
+ * Buffers for the md device that arrive via make_request are attached
+ * to the appropriate stripe in one of two lists linked on b_reqnext.
+ * One list (bh_read) for read requests, one (bh_write) for write.
+ * There should never be more than one buffer on the two lists
+ * together, but we are not guaranteed of that so we allow for more.
+ *
+ * If a buffer is on the read list when the associated cache buffer is
+ * Uptodate, the data is copied into the read buffer and it's b_end_io
+ * routine is called.  This may happen in the end_request routine only
+ * if the buffer has just successfully been read.  end_request should
+ * remove the buffers from the list and then set the Uptodate bit on
+ * the buffer.  Other threads may do this only if they first check
+ * that the Uptodate bit is set.  Once they have checked that they may
+ * take buffers off the read queue.
+ *
+ * When a buffer on the write list is committed for write it is copied
+ * into the cache buffer, which is then marked dirty, and moved onto a
+ * third list, the written list (bh_written).  Once both the parity
+ * block and the cached buffer are successfully written, any buffer on
+ * a written list can be returned with b_end_io.
+ *
+ * The write list and read list both act as fifos.  The read list is
+ * protected by the device_lock.  The write and written lists are
+ * protected by the stripe lock.  The device_lock, which can be
+ * claimed while the stipe lock is held, is only for list
+ * manipulations and will only be held for a very short time.  It can
+ * be claimed from interrupts.
+ *
+ *
+ * Stripes in the stripe cache can be on one of two lists (or on
+ * neither).  The "inactive_list" contains stripes which are not
+ * currently being used for any request.  They can freely be reused
+ * for another stripe.  The "handle_list" contains stripes that need
+ * to be handled in some way.  Both of these are fifo queues.  Each
+ * stripe is also (potentially) linked to a hash bucket in the hash
+ * table so that it can be found by sector number.  Stripes that are
+ * not hashed must be on the inactive_list, and will normally be at
+ * the front.  All stripes start life this way.
+ *
+ * The inactive_list, handle_list and hash bucket lists are all protected by the
+ * device_lock.
+ *  - stripes on the inactive_list never have their stripe_lock held.
+ *  - stripes have a reference counter. If count==0, they are on a list.
+ *  - If a stripe might need handling, STRIPE_HANDLE is set.
+ *  - When refcount reaches zero, then if STRIPE_HANDLE it is put on
+ *    handle_list else inactive_list
+ *
+ * This, combined with the fact that STRIPE_HANDLE is only ever
+ * cleared while a stripe has a non-zero count means that if the
+ * refcount is 0 and STRIPE_HANDLE is set, then it is on the
+ * handle_list and if recount is 0 and STRIPE_HANDLE is not set, then
+ * the stripe is on inactive_list.
+ *
+ * The possible transitions are:
+ *  activate an unhashed/inactive stripe (get_active_stripe())
+ *     lockdev check-hash unlink-stripe cnt++ clean-stripe hash-stripe unlockdev
+ *  activate a hashed, possibly active stripe (get_active_stripe())
+ *     lockdev check-hash if(!cnt++)unlink-stripe unlockdev
+ *  attach a request to an active stripe (add_stripe_bh())
+ *     lockdev attach-buffer unlockdev
+ *  handle a stripe (handle_stripe())
+ *     lockstripe clrSTRIPE_HANDLE ... (lockdev check-buffers unlockdev) .. change-state .. record io needed unlockstripe schedule io
+ *  release an active stripe (release_stripe())
+ *     lockdev if (!--cnt) { if  STRIPE_HANDLE, add to handle_list else add to inactive-list } unlockdev
+ *
+ * The refcount counts each thread that have activated the stripe,
+ * plus raid5d if it is handling it, plus one for each active request
+ * on a cached buffer.

+
+  To use rbtrees you'll have to implement your own insert and search cores.
+  This will avoid us to use callbacks and to drop drammatically performances.
+  I know it's not the cleaner way,  but in C (not in C++) to get
+  performances and genericity...
+
+  Some example of insert and search follows here. The search is a plain
+  normal search over an ordered tree. The insert instead must be implemented
+  int two steps: as first thing the code must insert the element in
+  order as a red leaf in the tree, then the support library function
+  rb_insert_color() must be called. Such function will do the
+  not trivial work to rebalance the rbtree if necessary.

+ * an RCU callback, (3) CPU 0 exits the RCU read-side critical section,
+ * (4) CPU 2 enters a RCU read-side critical section, (5) the RCU
+ * callback is invoked.  This is legal, because the RCU read-side critical
+ * section that was running concurrently with the call_rcu() (and which
+ * therefore might be referencing something that the corresponding RCU
+ * callback would free up) has completed before the corresponding
+ * RCU callback is invoked.

+/* These all interelate for performance.  
+**
+** If the journal block count is smaller than n transactions, you lose speed. 
+** I don't know what n is yet, I'm guessing 8-16.
+**
+** typical transaction size depends on the application, how often fsync is
+** called, and how many metadata blocks you dirty in a 30 second period.  
+** The more small files (<16k) you use, the larger your transactions will
+** be.
+** 
+** If your journal fills faster than dirty buffers get flushed to disk, it must flush them before allowing the journal
+** to wrap, which slows things down.  If you need high speed meta data updates, the journal should be big enough
+** to prevent wrapping before dirty meta blocks get to disk.
+**
+** If the batch max is smaller than the transaction max, you'll waste space at the end of the journal
+** because journal_end sets the next transaction to start at 0 if the next transaction has any chance of wrapping.
+**
+** The large the batch max age, the better the speed, and the more meta data changes you'll lose after a crash.

+/**
+ * struct security_operations - main security structure
+ *
+ * Security hooks for program execution operations.
+ *
+ * @bprm_alloc_security:
+ *      Allocate and attach a security structure to the @bprm->security field.
+ *      The security field is initialized to NULL when the bprm structure is
+ *      allocated.
+ *      @bprm contains the linux_binprm structure to be modified.
+ *      Return 0 if operation was successful.
+ * @bprm_free_security:
+ *      @bprm contains the linux_binprm structure to be modified.
+ *      Deallocate and clear the @bprm->security field.
+ * @bprm_apply_creds:
+ *      Compute and set the security attributes of a process being transformed
+ *      by an execve operation based on the old attributes (current->security)
+ *      and the information saved in @bprm->security by the set_security hook.
+ *      Since this hook function (and its caller) are void, this hook can not
+ *      return an error.  However, it can leave the security attributes of the
+ *      process unchanged if an access failure occurs at this point.
+ *      bprm_apply_creds is called under task_lock.  @unsafe indicates various
+ *      reasons why it may be unsafe to change security state.
+ *      @bprm contains the linux_binprm structure.
+ * @bprm_post_apply_creds:
+ *      Runs after bprm_apply_creds with the task_lock dropped, so that
+ *      functions which cannot be called safely under the task_lock can
+ *      be used.  This hook is a good place to perform state changes on
+ *      the process such as closing open file descriptors to which access
+ *      is no longer granted if the attributes were changed.
+ *      Note that a security module might need to save state between
+ *      bprm_apply_creds and bprm_post_apply_creds to store the decision
+ *      on whether the process may proceed.
+ *      @bprm contains the linux_binprm structure.
+ * @bprm_set_security:
+ *      Save security information in the bprm->security field, typically based
+ *      on information about the bprm->file, for later use by the apply_creds
+ *      hook.  This hook may also optionally check permissions (e.g. for
+ *      transitions between security domains).
+ *      This hook may be called multiple times during a single execve, e.g. for
+ *      interpreters.  The hook can tell whether it has already been called by
+ *      checking to see if @bprm->security is non-NULL.  If so, then the hook
+ *      may decide either to retain the security information saved earlier or
+ *      to replace it.
+ *      @bprm contains the linux_binprm structure.
+ *      Return 0 if the hook is successful and permission is granted.
+ * @bprm_check_security:
+ *      This hook mediates the point when a search for a binary handler will
+ *      begin.  It allows a check the @bprm->security value which is set in
+ *      the preceding set_security call.  The primary difference from
+ *      set_security is that the argv list and envp list are reliably
+ *      available in @bprm.  This hook may be called multiple times
+ *      during a single execve; and in each pass set_security is called
+ *      first.
+ *      @bprm contains the linux_binprm structure.
+ *      Return 0 if the hook is successful and permission is granted.
+ * @bprm_secureexec:
+ *      Return a boolean value (0 or 1) indicating whether a "secure exec" 
+ *      is required.  The flag is passed in the auxiliary table
+ *      on the initial stack to the ELF interpreter to indicate whether libc 
+ *      should enable secure mode.
+ *      @bprm contains the linux_binprm structure.
+ *
+ * Security hooks for filesystem operations.
+ *
+ * @sb_alloc_security:
+ *      Allocate and attach a security structure to the sb->s_security field.
+ *      The s_security field is initialized to NULL when the structure is
+ *      allocated.
+ *      @sb contains the super_block structure to be modified.
+ *      Return 0 if operation was successful.
+ * @sb_free_security:
+ *      Deallocate and clear the sb->s_security field.
+ *      @sb contains the super_block structure to be modified.
+ * @sb_statfs:
+ *      Check permission before obtaining filesystem statistics for the @sb
+ *      filesystem.
+ *      @sb contains the super_block structure for the filesystem.
+ *      Return 0 if permission is granted.  
+ * @sb_mount:
+ *      Check permission before an object specified by @dev_name is mounted on
+ *      the mount point named by @nd.  For an ordinary mount, @dev_name
+ *      identifies a device if the file system type requires a device.  For a
+ *      remount (@flags & MS_REMOUNT), @dev_name is irrelevant.  For a
+ *      loopback/bind mount (@flags & MS_BIND), @dev_name identifies the
+ *      pathname of the object being mounted.
+ *      @dev_name contains the name for object being mounted.
+ *      @nd contains the nameidata structure for mount point object.
+ *      @type contains the filesystem type.
+ *      @flags contains the mount flags.
+ *      @data contains the filesystem-specific data.
+ *      Return 0 if permission is granted.
+ * @sb_copy_data:
+ *      Allow mount option data to be copied prior to parsing by the filesystem,
+ *      so that the security module can extract security-specific mount
+ *      options cleanly (a filesystem may modify the data e.g. with strsep()).
+ *      This also allows the original mount data to be stripped of security-
+ *      specific options to avoid having to make filesystems aware of them.
+ *      @type the type of filesystem being mounted.
+ *      @orig the original mount data copied from userspace.
+ *      @copy copied data which will be passed to the security module.
+ *      Returns 0 if the copy was successful.
+ * @sb_check_sb:
+ *      Check permission before the device with superblock @mnt->sb is mounted
+ *      on the mount point named by @nd.
+ *      @mnt contains the vfsmount for device being mounted.
+ *      @nd contains the nameidata object for the mount point.
+ *      Return 0 if permission is granted.
+ * @sb_umount:
+ *      Check permission before the @mnt file system is unmounted.
+ *      @mnt contains the mounted file system.
+ *      @flags contains the unmount flags, e.g. MNT_FORCE.
+ *      Return 0 if permission is granted.
+ * @sb_umount_close:
+ *      Close any files in the @mnt mounted filesystem that are held open by
+ *      the security module.  This hook is called during an umount operation
+ *      prior to checking whether the filesystem is still busy.
+ *      @mnt contains the mounted filesystem.
+ * @sb_umount_busy:
+ *      Handle a failed umount of the @mnt mounted filesystem, e.g.  re-opening
+ *      any files that were closed by umount_close.  This hook is called during
+ *      an umount operation if the umount fails after a call to the
+ *      umount_close hook.
+ *      @mnt contains the mounted filesystem.
+ * @sb_post_remount:
+ *      Update the security module's state when a filesystem is remounted.
+ *      This hook is only called if the remount was successful.
+ *      @mnt contains the mounted file system.
+ *      @flags contains the new filesystem flags.
+ *      @data contains the filesystem-specific data.
+ * @sb_post_mountroot:
+ *      Update the security module's state when the root filesystem is mounted.
+ *      This hook is only called if the mount was successful.
+ * @sb_post_addmount:
+ *      Update the security module's state when a filesystem is mounted.
+ *      This hook is called any time a mount is successfully grafetd to
+ *      the tree.
+ *      @mnt contains the mounted filesystem.
+ *      @mountpoint_nd contains the nameidata structure for the mount point.
+ * @sb_pivotroot:
+ *      Check permission before pivoting the root filesystem.
+ *      @old_nd contains the nameidata structure for the new location of the current root (put_old).
+ *      @new_nd contains the nameidata structure for the new root (new_root).
+ *      Return 0 if permission is granted.
+ * @sb_post_pivotroot:
+ *      Update module state after a successful pivot.
+ *      @old_nd contains the nameidata structure for the old root.
+ *      @new_nd contains the nameidata structure for the new root.
+ *
+ * Security hooks for inode operations.
+ *
+ * @inode_alloc_security:
+ *      Allocate and attach a security structure to @inode->i_security.  The
+ *      i_security field is initialized to NULL when the inode structure is
+ *      allocated.
+ *      @inode contains the inode structure.
+ *      Return 0 if operation was successful.
+ * @inode_free_security:
+ *      @inode contains the inode structure.
+ *      Deallocate the inode security structure and set @inode->i_security to
+ *      NULL. 
+ * @inode_create:
+ *      Check permission to create a regular file.
+ *      @dir contains inode structure of the parent of the new file.
+ *      @dentry contains the dentry structure for the file to be created.

+ *      @dir contains the inode structure of the parent directory of the new file.
+ *      @dentry contains the the dentry structure for the newly created file.

+ *      Return 0 if permission is granted.

+ *      Check permissions when creating a special file (or a socket or a fifo
+ *      file created via the mknod system call).  Note that if mknod operation
+ *      is being done for a regular file, then the create hook will be called
+ *      and not this hook.

+ *
+ * Security hooks for file operations
+ *
+ * @file_permission:
+ *      Check file permissions before accessing an open file.  This hook is
+ *      called by various operations that read or write files.  A security
+ *      module can use this hook to perform additional checking on these
+ *      operations, e.g.  to revalidate permissions on use to support privilege
+ *      bracketing or policy changes.  Notice that this hook is used when the
+ *      actual read/write operations are performed, whereas the
+ *      inode_security_ops hook is called when a file is opened (as well as
+ *      many other operations).
+ *      Caveat:  Although this hook can be used to revalidate permissions for
+ *      various system call operations that read or write files, it does not
+ *      address the revalidation of permissions for memory-mapped files.
+ *      Security modules must handle this separately if they need such
+ *      revalidation.

+ *      @mask contains the requested permissions.
+ *      Return 0 if permission is granted.
+ * @file_alloc_security:

+ *      @cmd contains the operation to perform.
+ *      @arg contains the operational arguments.
+ *      Check permission for an ioctl operation on @file.  Note that @arg can
+ *      sometimes represents a user space pointer; in other cases, it may be a
+ *      simple integer value.  When @arg represents a user space pointer, it
+ *      should never be used by the security module.
+ *      Return 0 if permission is granted.

+ *      Check permissions for a mmap operation.  The @file may be NULL, e.g.
+ *      if mapping anonymous memory.

+ *      Check permission before allowing the file operation specified by @cmd
+ *      from being performed on the file @file.  Note that @arg can sometimes
+ *      represents a user space pointer; in other cases, it may be a simple
+ *      integer value.  When @arg represents a user space pointer, it should
+ *      never be used by the security module.
+ *      @file contains the file structure.

+ * @file_send_sigiotask:
+ *      Check permission for the file owner @fown to send SIGIO or SIGURG to the

+ *      struct file, so the file structure (and associated security information)
+ *      can always be obtained:
+ *              (struct file *)((long)fown - offsetof(struct file,f_owner));
+ *      @tsk contains the structure of task receiving signal.
+ *      @fown contains the file owner information.
+ *      @sig is the signal that will be sent.  When 0, kernel sends SIGIO.

+ * and permission hooks in inode_security_ops), binding and connecting to
+ * sockets in the abstract name space is completely unmediated.  Sufficient
+ * control of Unix domain sockets in the abstract name space isn't possible
+ * using only the socket layer hooks, since we need to know the actual target
+ * socket, which is not looked up until we are inside the af_unix code.

+ *      in the associated inode.  Typically, the inode alloc_security hook will
+ *      allocate and and attach security information to
+ *      sock->inode->i_security.  This hook may be used to update the

+ *      @sock contains the listening socket structure.
+ *      @newsock contains the newly created server socket for connection.

+ *      Return 0 if permission is granted.
+ * @socket_sock_rcv_skb:
+ *      Check permissions on incoming network packets.  This hook is distinct
+ *      from Netfilter's IP input hooks since it is the first time that the
+ *      incoming sk_buff @skb has been associated with a particular socket, @sk.
+ *      @sk contains the sock (not socket) associated with the incoming sk_buff.

+ * @sem_free_security:
+ *      deallocate security struct for this semaphore
+ *      @sma contains the semaphore structure.
+ * @sem_associate:
+ *      Check permission when a semaphore is requested through the semget

+ *      created.
+ *      @sma contains the semaphore structure.
+ *      @semflg contains the operation control flags.
+ *      Return 0 if permission is granted.
+ * @sem_semctl:

+ *      IPC_INFO or SEM_INFO.
+ *      @sma contains the semaphore structure.  May be NULL.
+ *      @cmd contains the operation to be performed.
+ *      Return 0 if permission is granted.

+ *      may be modified.
+ *      @sma contains the semaphore structure.
+ *      @sops contains the operations to perform.
+ *      @nsops contains the number of operations to perform.

+ *      Return 0 if permission is granted.
+ *
+ * @ptrace:
+ *      Check permission before allowing the @parent process to trace the
+ *      @child process.
+ *      Security modules may also want to perform a process tracing check
+ *      during an execve in the set_security or apply_creds hooks of
+ *      binprm_security_ops if the process is being traced and its security
+ *      attributes would be changed by the execve.
+ *      @parent contains the task_struct structure for parent process.
+ *      @child contains the task_struct structure for child process.
+ *      Return 0 if permission is granted.
+ * @capget:
+ *      Get the @effective, @inheritable, and @permitted capability sets for
+ *      the @target process.  The hook may also perform permission checking to
+ *      determine if the current process is allowed to see the capability sets
+ *      of the @target process.
+ *      @target contains the task_struct structure for target process.
+ *      @effective contains the effective capability set.
+ *      @inheritable contains the inheritable capability set.
+ *      @permitted contains the permitted capability set.

+ * @capset_check:
+ *      Check permission before setting the @effective, @inheritable, and
+ *      @permitted capability sets for the @target process.
+ *      Caveat:  @target is also set to current if a set of processes is
+ *      specified (i.e. all processes other than current and init or a
+ *      particular process group).  Hence, the capset_set hook may need to
+ *      revalidate permission to the actual target process.
+ *      @target contains the task_struct structure for target process.
+ *      @effective contains the effective capability set.
+ *      @inheritable contains the inheritable capability set.
+ *      @permitted contains the permitted capability set.
+ *      Return 0 if permission is granted.
+ * @capset_set:
+ *      Set the @effective, @inheritable, and @permitted capability sets for
+ *      the @target process.  Since capset_check cannot always check permission
+ *      to the real @target process, this hook may also perform permission
+ *      checking to determine if the current process is allowed to set the
+ *      capability sets of the @target process.  However, this hook has no way
+ *      of returning an error due to the structure of the sys_capset code.
+ *      @target contains the task_struct structure for target process.
+ *      @effective contains the effective capability set.
+ *      @inheritable contains the inheritable capability set.
+ *      @permitted contains the permitted capability set.
+ * @acct:
+ *      Check permission before enabling or disabling process accounting.  If
+ *      accounting is being enabled, then @file refers to the open file used to
+ *      store accounting records.  If accounting is being disabled, then @file
+ *      is NULL.
+ *      @file contains the file structure for the accounting file (may be NULL).
+ *      Return 0 if permission is granted.
+ * @sysctl:
+ *      Check permission before accessing the @table sysctl variable in the
+ *      manner specified by @op.
+ *      @table contains the ctl_table structure for the sysctl variable.
+ *      @op contains the operation (001 = search, 002 = write, 004 = read).
+ *      Return 0 if permission is granted.
+ * @capable:
+ *      Check whether the @tsk process has the @cap capability.
+ *      @tsk contains the task_struct for the process.
+ *      @cap contains the capability <include/linux/capability.h>.
+ *      Return 0 if the capability is granted for @tsk.
+ * @syslog:
+ *      Check permission before accessing the kernel message ring or changing
+ *      logging to the console.
+ *      See the syslog(2) manual page for an explanation of the @type values.  
+ *      @type contains the type of action.
+ *      Return 0 if permission is granted.
+ * @settime:
+ *      Check permission to change the system time.
+ *      struct timespec and timezone are defined in include/linux/time.h
+ *      @ts contains new time
+ *      @tz contains new timezone
+ *      Return 0 if permission is granted.
+ * @vm_enough_memory:
+ *      Check permissions for allocating a new virtual mapping.
+ *      @pages contains the number of pages.
+ *      Return 0 if permission is granted.
+ *
+ * @register_security:
+ *      allow module stacking.
+ *      @name contains the name of the security module being stacked.
+ *      @ops contains a pointer to the struct security_operations of the module to stack.
+ * @unregister_security:
+ *      remove a stacked module.
+ *      @name contains the name of the security module being unstacked.
+ *      @ops contains a pointer to the struct security_operations of the module to unstack.
+ * 
+ * This is the main security structure.

+ *
+ *      HW: the most generic way. Device supplied checksum of _all_

+ *          NOTE: Even if device supports only some protocols, but
+ *          is able to produce some skb->csum, it MUST use HW,
+ *          not UNNECESSARY.
+ *
+ * B. Checksumming on output.
+ *
+ *      NONE: skb is checksummed by protocol or csum is not required.
+ *
+ *      HW: device is required to csum packet as seen by hard_start_xmit
+ *      from skb->h.raw to the end and to record the checksum
+ *      at skb->h.raw+skb->csum.
+ *
+ *      Device must show its capabilities in dev->features, set
+ *      at device setup time.
+ *      NETIF_F_HW_CSUM - it is clever device, it is able to checksum
+ *                        everything.
+ *      NETIF_F_NO_CSUM - loopback or reliable single hop media.
+ *      NETIF_F_IP_CSUM - device is dumb. It is able to csum only
+ *                        TCP/UDP over IPv4. Sigh. Vendors like this
+ *                        way by an unknown reason. Though, see comment above

+ * TEST, the function will try to find a matching cache entry in the cache.

+ *    If no entry is found, a new non-VALID entry is created.
+ * If "set" == 1 and INPLACE == 0 :
+ *    If no entry is found a new one is inserted with data from "template"
+ *    If a non-CACHE_VALID entry is found, it is updated from template using UPDATE
+ *    If a CACHE_VALID entry is found, a new entry is swapped in with data
+ *       from "template"
+ * If set == 1, and INPLACE == 1 :
+ *    As above, except that if a CACHE_VALID entry is found, we UPDATE in place
+ *       instead of swapping in a new entry.
+ *
+ * If the passed handle has the CACHE_NEGATIVE flag set, then UPDATE is not
+ * run but insteead CACHE_NEGATIVE is set in any new item.
+
+ *  In any case, the new entry is returned with a reference count.
+ *
+ *    
+ * RTN is a struct type for a cache entry
+ * MEMBER is the member of the cache which is cache_head, which must be first
+ * FNAME is the name for the function   
+ * ARGS are arguments to function and must contain RTN *item, int set.  May
+ *   also contain something to be usedby SETUP or DETAIL to find cache_detail.
+ * SETUP  locates the cache detail and makes it available as...
+ * DETAIL identifies the cache detail, possibly set up by SETUP
+ * HASHFN returns a hash value of the cache entry "item"
+ * TEST  tests if "tmp" matches "item"
+ * INIT copies key information from "item" to "new"
+ * UPDATE copies content information from "item" to "tmp"
+ * INPLACE is true if updates can happen inplace rather than allocating a new structure

+ * under /proc; non-leaf nodes will be represented by directories.  A
+ * null procname disables /proc mirroring at this node.
+ * 
+ * sysctl(2) can automatically manage read and write requests through
+ * the sysctl table.  The data and maxlen fields of the ctl_table
+ * struct enable minimal validation of the values being written to be
+ * performed, and the mode field allows minimal authentication.
+ * 
+ * More sophisticated management can be enabled by the provision of a
+ * strategy routine with the table entry.  This will be called before
+ * any automatic read or write of the data is performed.
+ * 
+ * The strategy routine may return:
+ * <0: Error occurred (error is passed to user process)
+ * 0:  OK - proceed with automatic read or write.
+ * >0: OK - read or write has been done by the strategy routine, so 
+ *     return immediately.
+ * 
+ * There must be a proc_handler routine for any terminal nodes
+ * mirrored under /proc/sys (non-terminals are handled by a built-in
+ * directory handler).  Several default handlers are available to
+ * cover common cases.

+ * This structure defines the interface between the low-level tty
+ * driver and the tty routines.  The following routines can be
+ * defined; unless noted otherwise, they are optional, and can be
+ * filled in with a null pointer.
+ *
+ * int  (*open)(struct tty_struct * tty, struct file * filp);
+ *
+ *      This routine is called when a particular tty device is opened.
+ *      This routine is mandatory; if this routine is not filled in,
+ *      the attempted open will fail with ENODEV.
+ *     
+ * void (*close)(struct tty_struct * tty, struct file * filp);
+ *
+ *      This routine is called when a particular tty device is closed.
+ *
+ * int (*write)(struct tty_struct * tty,
+ *               const unsigned char *buf, int count);
+ *
+ *      This routine is called by the kernel to write a series of
+ *      characters to the tty device.  The characters may come from
+ *      user space or kernel space.  This routine will return the
+ *      number of characters actually accepted for writing.  This
+ *      routine is mandatory.
+ *
+ * void (*put_char)(struct tty_struct *tty, unsigned char ch);
+ *
+ *      This routine is called by the kernel to write a single
+ *      character to the tty device.  If the kernel uses this routine,
+ *      it must call the flush_chars() routine (if defined) when it is
+ *      done stuffing characters into the driver.  If there is no room
+ *      in the queue, the character is ignored.
+ *
+ * void (*flush_chars)(struct tty_struct *tty);
+ *
+ *      This routine is called by the kernel after it has written a
+ *      series of characters to the tty device using put_char().  
+ * 
+ * int  (*write_room)(struct tty_struct *tty);
+ *
+ *      This routine returns the numbers of characters the tty driver
+ *      will accept for queuing to be written.  This number is subject
+ *      to change as output buffers get emptied, or if the output flow
+ *      control is acted.
+ * 
+ * int  (*ioctl)(struct tty_struct *tty, struct file * file,
+ *          unsigned int cmd, unsigned long arg);
+ *
+ *      This routine allows the tty driver to implement
+ *      device-specific ioctl's.  If the ioctl number passed in cmd
+ *      is not recognized by the driver, it should return ENOIOCTLCMD.
+ * 
+ * void (*set_termios)(struct tty_struct *tty, struct termios * old);
+ *
+ *      This routine allows the tty driver to be notified when
+ *      device's termios settings have changed.  Note that a
+ *      well-designed tty driver should be prepared to accept the case
+ *      where old == NULL, and try to do something rational.
+ *
+ * void (*set_ldisc)(struct tty_struct *tty);
+ *
+ *      This routine allows the tty driver to be notified when the
+ *      device's termios settings have changed.
+ * 
+ * void (*throttle)(struct tty_struct * tty);
+ *
+ *      This routine notifies the tty driver that input buffers for
+ *      the line discipline are close to full, and it should somehow
+ *      signal that no more characters should be sent to the tty.
+ * 
+ * void (*unthrottle)(struct tty_struct * tty);
+ *
+ *      This routine notifies the tty drivers that it should signals
+ *      that characters can now be sent to the tty without fear of
+ *      overrunning the input buffers of the line disciplines.
+ * 
+ * void (*stop)(struct tty_struct *tty);
+ *
+ *      This routine notifies the tty driver that it should stop
+ *      outputting characters to the tty device.  
+ * 
+ * void (*start)(struct tty_struct *tty);
+ *
+ *      This routine notifies the tty driver that it resume sending
+ *      characters to the tty device.
+ * 
+ * void (*hangup)(struct tty_struct *tty);
+ *
+ *      This routine notifies the tty driver that it should hangup the
+ *      tty device.
+ *
+ * void (*break_ctl)(struct tty_stuct *tty, int state);
+ *
+ *      This optional routine requests the tty driver to turn on or
+ *      off BREAK status on the RS-232 port.  If state is -1,
+ *      then the BREAK status should be turned on; if state is 0, then
+ *      BREAK should be turned off.
+ *
+ *      If this routine is implemented, the high-level tty driver will
+ *      handle the following ioctls: TCSBRK, TCSBRKP, TIOCSBRK,
+ *      TIOCCBRK.  Otherwise, these ioctls will be passed down to the
+ *      driver to handle.
+ *
+ * void (*wait_until_sent)(struct tty_struct *tty, int timeout);
+ * 
+ *      This routine waits until the device has written out all of the
+ *      characters in its transmitter FIFO.
+ *
+ * void (*send_xchar)(struct tty_struct *tty, char ch);
+ *
+ *      This routine is used to send a high-priority XON/XOFF
+ *      character to the device.

+ *
+ *      This function is called when the line discipline is being
+ *      shutdown, either because the tty is being closed or because
+ *      the tty is being changed to use a new line discipline
+ * 
+ * void (*flush_buffer)(struct tty_struct *tty);
+ *
+ *      This function instructs the line discipline to clear its
+ *      buffers of any input characters it may have queued to be
+ *      delivered to the user mode process.
+ * 
+ * ssize_t (*chars_in_buffer)(struct tty_struct *tty);
+ *
+ *      This function returns the number of input characters the line
+ *      discipline may have queued up to be delivered to the user mode
+ *      process.
+ * 
+ * ssize_t (*read)(struct tty_struct * tty, struct file * file,
+ *                 unsigned char * buf, size_t nr);
+ *
+ *      This function is called when the user requests to read from
+ *      the tty.  The line discipline will return whatever characters
+ *      it has buffered up for the user.  If this function is not
+ *      defined, the user will receive an EIO error.
+ * 
+ * ssize_t (*write)(struct tty_struct * tty, struct file * file,
+ *                  const unsigned char * buf, size_t nr);
+ *
+ *      This function is called when the user requests to write to the
+ *      tty.  The line discipline will deliver the characters to the
+ *      low-level tty device for transmission, optionally performing
+ *      some processing on the characters first.  If this function is
+ *      not defined, the user will receive an EIO error.
+ * 
+ * int  (*ioctl)(struct tty_struct * tty, struct file * file,
+ *               unsigned int cmd, unsigned long arg);
+ *
+ *      This function is called when the user requests an ioctl which
+ *      is not handled by the tty layer or the low-level tty driver.
+ *      It is intended for ioctls which affect line discpline
+ *      operation.  Note that the search order for ioctls is (1) tty
+ *      layer, (2) tty low-level driver, (3) line discpline.  So a
+ *      low-level driver can "grab" an ioctl request before the line
+ *      discpline has a chance to see it.
+ * 
+ * void (*set_termios)(struct tty_struct *tty, struct termios * old);
+ *
+ *      This function notifies the line discpline that a change has
+ *      been made to the termios structure.
+ * 
+ * int  (*poll)(struct tty_struct * tty, struct file * file,
+ *                poll_table *wait);
+ *
+ *      This function is called when a user attempts to select/poll on a
+ *      tty device.  It is solely the responsibility of the line
+ *      discipline to handle poll requests.
+ *
+ * void (*receive_buf)(struct tty_struct *, const unsigned char *cp,
+ *                     char *fp, int count);
+ *
+ *      This function is called by the low-level tty driver to send
+ *      characters received by the hardware to the line discpline for
+ *      processing.  <cp> is a pointer to the buffer of input
+ *      character received by the device.  <fp> is a pointer to a
+ *      pointer of flag bytes which indicate whether a character was
+ *      received with a parity error, etc.
+ * 
+ * int  (*receive_room)(struct tty_struct *);
+ *
+ *      This function is called by the low-level tty driver to
+ *      determine how many characters the line discpline can accept.
+ *      The low-level driver must not send more characters than was
+ *      indicated by receive_room, or the line discpline may drop
+ *      those characters.
+ * 
+ * void (*write_wakeup)(struct tty_struct *);
+ *
+ *      This function is called by the low-level tty driver to signal
+ *      that line discpline should try to send more characters to the
+ *      low-level driver for transmission.  If the line discpline does
+ *      not have any more data to send, it can just return.
+ *
+ * int (*hangup)(struct tty_struct *)
+ *
+ *      Called on a hangup. Tells the discipline that it should
+ *      cease I/O to the tty driver. Can sleep. The driver should
+ *      seek to perform this action quickly but should wait until
+ *      any pending driver I/O is completed.

+ * Each disk drive contains some number of filesystems.
+ * A filesystem consists of a number of cylinder groups.
+ * Each cylinder group has inodes and data.
+ *
+ * A filesystem is described by its super-block, which in turn
+ * describes the cylinder groups.  The super-block is critical
+ * data and is replicated in each cylinder group to protect against
+ * catastrophic loss.  This is done at `newfs' time and the critical
+ * super-block data does not change, so the copies need not be
+ * referenced further unless disaster strikes.
+ *
+ * For filesystem fs, the offsets of the various blocks of interest
+ * are given in the super block as:
+ *      [fs->fs_sblkno]         Super-block
+ *      [fs->fs_cblkno]         Cylinder group block
+ *      [fs->fs_iblkno]         Inode blocks
+ *      [fs->fs_dblkno]         Data blocks
+ * The beginning of cylinder group cg in fs, is given by
+ * the ``cgbase(fs, cg)'' macro.
+ *
+ * Depending on the architecture and the media, the superblock may
+ * reside in any one of four places. For tiny media where every block
+ * counts, it is placed at the very front of the partition. Historically,
+ * UFS1 placed it 8K from the front to leave room for the disk label and
+ * a small bootstrap. For UFS2 it got moved to 64K from the front to leave
+ * room for the disk label and a bigger bootstrap, and for really piggy
+ * systems we check at 256K from the front if the first three fail. In
+ * all cases the size of the superblock will be SBLOCKSIZE. All values are
+ * given in byte-offset form, so they do not imply a sector size. The
+ * SBLOCKSEARCH specifies the order in which the locations should be searched.

+/* To write a force-feedback-capable driver, the upload_effect
+ * and erase_effect callbacks in input_dev must be implemented.
+ * The uinput driver will generate a fake input event when one of
+ * these callbacks are invoked. The userspace code then uses
+ * ioctls to retrieve additional parameters and send the return code.
+ * The callback blocks until this return code is sent.
+ *
+ * The described callback mechanism is only used if EV_FF is set.
+ * Otherwise, default implementations of upload_effect and erase_effect
+ * are used.
+ *
+ * To implement upload_effect():
+ *   1. Wait for an event with type==EV_UINPUT and code==UI_FF_UPLOAD.
+ *      A request ID will be given in 'value'.
+ *   2. Allocate a uinput_ff_upload struct, fill in request_id with
+ *      the 'value' from the EV_UINPUT event.
+ *   3. Issue a UI_BEGIN_FF_UPLOAD ioctl, giving it the
+ *      uinput_ff_upload struct. It will be filled in with the
+ *      ff_effect passed to upload_effect().
+ *   4. Perform the effect upload, and place the modified ff_effect
+ *      and a return code back into the uinput_ff_upload struct.
+ *   5. Issue a UI_END_FF_UPLOAD ioctl, also giving it the
+ *      uinput_ff_upload_effect struct. This will complete execution
+ *      of our upload_effect() handler.
+ *
+ * To implement erase_effect():

+ * @driver: the USB driver that is bound to this interface.
+ * @minor: the minor number assigned to this interface, if this
+ *      interface is bound to a driver that uses the USB major number.
+ *      If this interface does not use the USB major, this field should
+ *      be unused.  The driver should set this value in the probe()
+ *      function of the driver, after it has been assigned a minor
+ *      number from the USB core by calling usb_register_dev().
+ * @condition: binding state of the interface: not bound, binding
+ *      (in probe()), bound to a driver, or unbinding (in disconnect())
+ * @dev: driver model's view of this device
+ * @class_dev: driver model's class view of this device.
+ *
+ * USB device drivers attach to interfaces on a physical device.  Each
+ * interface encapsulates a single high level function, such as feeding
+ * an audio stream to a speaker or reporting a change in a volume control.
+ * Many USB devices only have one interface.  The protocol used to talk to
+ * an interface's endpoints can be defined in a usb "class" specification,
+ * or by a product's vendor.  The (default) control endpoint is part of
+ * every interface, but is never listed among the interface's descriptors.
+ *
+ * The driver that is bound to the interface can use standard driver model
+ * calls such as dev_get_drvdata() on the dev member of this structure.
+ *
+ * Each interface may have alternate settings.  The initial configuration
+ * of a device sets altsetting 0, but the device driver can change
+ * that setting using usb_set_interface().  Alternate settings are often
+ * used to control the the use of periodic endpoints, such as by having
+ * different endpoints use different amounts of reserved USB bandwidth.
+ * All standards-conformant USB devices that use isochronous endpoints
+ * will use them in non-default settings.
+ *
+ * The USB specification says that alternate setting numbers must run from
+ * 0 to one less than the total number of alternate settings.  But some
+ * devices manage to mess this up, and the structures aren't necessarily
+ * stored in numerical order anyhow.  Use usb_altnum_to_altsetting() to
+ * look up an alternate setting in the altsetting array based on its number.

+/**
+ * struct urb - USB Request Block
+ * @urb_list: For use by current owner of the URB.
+ * @pipe: Holds endpoint number, direction, type, and more.
+ *      Create these values with the eight macros available;
+ *      usb_{snd,rcv}TYPEpipe(dev,endpoint), where the TYPE is "ctrl"
+ *      (control), "bulk", "int" (interrupt), or "iso" (isochronous).
+ *      For example usb_sndbulkpipe() or usb_rcvintpipe().  Endpoint
+ *      numbers range from zero to fifteen.  Note that "in" endpoint two
+ *      is a different endpoint (and pipe) from "out" endpoint two.
+ *      The current configuration controls the existence, type, and
+ *      maximum packet size of any given endpoint.
+ * @dev: Identifies the USB device to perform the request.
+ * @status: This is read in non-iso completion functions to get the
+ *      status of the particular request.  ISO requests only use it
+ *      to tell whether the URB was unlinked; detailed status for
+ *      each frame is in the fields of the iso_frame-desc.
+ * @transfer_flags: A variety of flags may be used to affect how URB
+ *      submission, unlinking, or operation are handled.  Different
+ *      kinds of URB can use different flags.
+ * @transfer_buffer:  This identifies the buffer to (or from) which
+ *      the I/O request will be performed (unless URB_NO_TRANSFER_DMA_MAP
+ *      is set).  This buffer must be suitable for DMA; allocate it with
+ *      kmalloc() or equivalent.  For transfers to "in" endpoints, contents
+ *      of this buffer will be modified.  This buffer is used for the data
+ *      stage of control transfers.
+ * @transfer_dma: When transfer_flags includes URB_NO_TRANSFER_DMA_MAP,
+ *      the device driver is saying that it provided this DMA address,
+ *      which the host controller driver should use in preference to the
+ *      transfer_buffer.
+ * @transfer_buffer_length: How big is transfer_buffer.  The transfer may
+ *      be broken up into chunks according to the current maximum packet
+ *      size for the endpoint, which is a function of the configuration
+ *      and is encoded in the pipe.  When the length is zero, neither
+ *      transfer_buffer nor transfer_dma is used.
+ * @actual_length: This is read in non-iso completion functions, and
+ *      it tells how many bytes (out of transfer_buffer_length) were
+ *      transferred.  It will normally be the same as requested, unless
+ *      either an error was reported or a short read was performed.
+ *      The URB_SHORT_NOT_OK transfer flag may be used to make such
+ *      short reads be reported as errors. 
+ * @setup_packet: Only used for control transfers, this points to eight bytes
+ *      of setup data.  Control transfers always start by sending this data
+ *      to the device.  Then transfer_buffer is read or written, if needed.
+ * @setup_dma: For control transfers with URB_NO_SETUP_DMA_MAP set, the
+ *      device driver has provided this DMA address for the setup packet.
+ *      The host controller driver should use this in preference to
+ *      setup_packet.
+ * @start_frame: Returns the initial frame for isochronous transfers.
+ * @number_of_packets: Lists the number of ISO transfer buffers.
+ * @interval: Specifies the polling interval for interrupt or isochronous
+ *      transfers.  The units are frames (milliseconds) for for full and low
+ *      speed devices, and microframes (1/8 millisecond) for highspeed ones.
+ * @error_count: Returns the number of ISO transfers that reported errors.
+ * @context: For use in completion functions.  This normally points to
+ *      request-specific driver context.
+ * @complete: Completion handler. This URB is passed as the parameter to the
+ *      completion function.  The completion function may then do what
+ *      it likes with the URB, including resubmitting or freeing it.
+ * @iso_frame_desc: Used to provide arrays of ISO transfer buffers and to 
+ *      collect the transfer status for each buffer.
+ *
+ * This structure identifies USB transfer requests.  URBs must be allocated by
+ * calling usb_alloc_urb() and freed with a call to usb_free_urb().
+ * Initialization may be done using various usb_fill_*_urb() functions.  URBs
+ * are submitted using usb_submit_urb(), and pending requests may be canceled
+ * using usb_unlink_urb() or usb_kill_urb().
+ *
+ * Data Transfer Buffers:
+ *
+ * Normally drivers provide I/O buffers allocated with kmalloc() or otherwise
+ * taken from the general page pool.  That is provided by transfer_buffer
+ * (control requests also use setup_packet), and host controller drivers
+ * perform a dma mapping (and unmapping) for each buffer transferred.  Those
+ * mapping operations can be expensive on some platforms (perhaps using a dma
+ * bounce buffer or talking to an IOMMU),
+ * although they're cheap on commodity x86 and ppc hardware.
+ *
+ * Alternatively, drivers may pass the URB_NO_xxx_DMA_MAP transfer flags,
+ * which tell the host controller driver that no such mapping is needed since
+ * the device driver is DMA-aware.  For example, a device driver might
+ * allocate a DMA buffer with usb_buffer_alloc() or call usb_buffer_map().
+ * When these transfer flags are provided, host controller drivers will
+ * attempt to use the dma addresses found in the transfer_dma and/or
+ * setup_dma fields rather than determining a dma address themselves.  (Note
+ * that transfer_buffer and setup_packet must still be set because not all
+ * host controllers use DMA, nor do virtual root hubs).
+ *
+ * Initialization:
+ *
+ * All URBs submitted must initialize the dev, pipe, transfer_flags (may be
+ * zero), and complete fields.
+ * The URB_ASYNC_UNLINK transfer flag affects later invocations of
+ * the usb_unlink_urb() routine.  Note: Failure to set URB_ASYNC_UNLINK
+ * with usb_unlink_urb() is deprecated.  For synchronous unlinks use
+ * usb_kill_urb() instead.
+ *
+ * All URBs must also initialize 
+ * transfer_buffer and transfer_buffer_length.  They may provide the
+ * URB_SHORT_NOT_OK transfer flag, indicating that short reads are
+ * to be treated as errors; that flag is invalid for write requests.
+ *
+ * Bulk URBs may
+ * use the URB_ZERO_PACKET transfer flag, indicating that bulk OUT transfers
+ * should always terminate with a short packet, even if it means adding an
+ * extra zero length packet.
+ *
+ * Control URBs must provide a setup_packet.  The setup_packet and
+ * transfer_buffer may each be mapped for DMA or not, independently of
+ * the other.  The transfer_flags bits URB_NO_TRANSFER_DMA_MAP and
+ * URB_NO_SETUP_DMA_MAP indicate which buffers have already been mapped.
+ * URB_NO_SETUP_DMA_MAP is ignored for non-control URBs.
+ *
+ * Interrupt URBs must provide an interval, saying how often (in milliseconds
+ * or, for highspeed devices, 125 microsecond units)
+ * to poll for transfers.  After the URB has been submitted, the interval
+ * field reflects how the transfer was actually scheduled.
+ * The polling interval may be more frequent than requested.
+ * For example, some controllers have a maximum interval of 32 milliseconds,
+ * while others support intervals of up to 1024 milliseconds.
+ * Isochronous URBs also have transfer intervals.  (Note that for isochronous
+ * endpoints, as well as high speed interrupt endpoints, the encoding of
+ * the transfer interval in the endpoint descriptor is logarithmic.
+ * Device drivers must convert that value to linear units themselves.)
+ *
+ * Isochronous URBs normally use the URB_ISO_ASAP transfer flag, telling
+ * the host controller to schedule the transfer as soon as bandwidth
+ * utilization allows, and then set start_frame to reflect the actual frame
+ * selected during submission.  Otherwise drivers must specify the start_frame
+ * and handle the case where the transfer can't begin then.  However, drivers
+ * won't know how bandwidth is currently allocated, and while they can
+ * find the current frame using usb_get_current_frame_number () they can't
+ * know the range for that frame number.  (Ranges for frame counter values
+ * are HC-specific, and can go from 256 to 65536 frames from "now".)
+ *
+ * Isochronous URBs have a different data transfer model, in part because
+ * the quality of service is only "best effort".  Callers provide specially
+ * allocated URBs, with number_of_packets worth of iso_frame_desc structures
+ * at the end.  Each such packet is an individual ISO transfer.  Isochronous
+ * URBs are normally queued, submitted by drivers to arrange that
+ * transfers are at least double buffered, and then explicitly resubmitted
+ * in completion handlers, so
+ * that data (such as audio or video) streams at as constant a rate as the
+ * host controller scheduler can support.
+ *
+ * Completion Callbacks:
+ *
+ * The completion callback is made in_interrupt(), and one of the first
+ * things that a completion handler should do is check the status field.
+ * The status field is provided for all URBs.  It is used to report
+ * unlinked URBs, and status for all non-ISO transfers.  It should not
+ * be examined before the URB is returned to the completion handler.
+ *
+ * The context field is normally used to link URBs back to the relevant
+ * driver or request state.
+ *
+ * When the completion callback is invoked for non-isochronous URBs, the
+ * actual_length field tells how many bytes were transferred.  This field
+ * is updated even when the URB terminated with an error or was unlinked.
+ *
+ * ISO transfer status is reported in the status and actual_length fields
+ * of the iso_frame_desc array, and the number of errors is reported in
+ * error_count.  Completion callbacks for ISO transfers will normally
+ * (re)submit URBs to ensure a constant transfer rate.

+/**
+ * struct usb_request - describes one i/o request
+ * @buf: Buffer used for data.  Always provide this; some controllers
+ *      only use PIO, or don't use DMA for some endpoints.
+ * @dma: DMA address corresponding to 'buf'.  If you don't set this
+ *      field, and the usb controller needs one, it is responsible
+ *      for mapping and unmapping the buffer.
+ * @length: Length of that data
+ * @no_interrupt: If true, hints that no completion irq is needed.
+ *      Helpful sometimes with deep request queues that are handled
+ *      directly by DMA controllers.
+ * @zero: If true, when writing data, makes the last packet be "short"
+ *     by adding a zero length packet as needed;
+ * @short_not_ok: When reading data, makes short packets be
+ *     treated as errors (queue stops advancing till cleanup).
+ * @complete: Function called when request completes, so this request and
+ *      its buffer may be re-used.
+ *      Reads terminate with a short packet, or when the buffer fills,
+ *      whichever comes first.  When writes terminate, some data bytes
+ *      will usually still be in flight (often in a hardware fifo).
+ *      Errors (for reads or writes) stop the queue from advancing
+ *      until the completion function returns, so that any transfers
+ *      invalidated by the error may first be dequeued.
+ * @context: For use by the completion callback
+ * @list: For use by the gadget driver.
+ * @status: Reports completion code, zero or a negative errno.
+ *      Normally, faults block the transfer queue from advancing until
+ *      the completion callback returns.
+ *      Code "-ESHUTDOWN" indicates completion caused by device disconnect,
+ *      or when the driver disabled the endpoint.
+ * @actual: Reports bytes transferred to/from the buffer.  For reads (OUT
+ *      transfers) this may be less than the requested length.  If the
+ *      short_not_ok flag is set, short reads are treated as errors
+ *      even when status otherwise indicates successful completion.
+ *      Note that for writes (IN transfers) some data bytes may still
+ *      reside in a device-side FIFO when the request is reported as
+ *      complete.
+ *
+ * These are allocated/freed through the endpoint they're used with.  The
+ * hardware's driver can add extra per-request data to the memory it returns,
+ * which often avoids separate memory allocations (potential failures),
+ * later when the request is queued.
+ *
+ * Request flags affect request handling, such as whether a zero length
+ * packet is written (the "zero" flag), whether a short read should be
+ * treated as an error (blocking request queue advance, the "short_not_ok"
+ * flag), or hinting that an interrupt is not required (the "no_interrupt"
+ * flag, for use with deep request queues).
+ *
+ * Bulk endpoints can use any size buffers, and can also be used for interrupt
+ * transfers. interrupt-only endpoints can be much less functional.

+ * protocols since not all usb hardware can successfully handle zero length
+ * packets.  (ZLPs may be explicitly written, and may be implicitly written if
+ * the request 'zero' flag is set.)  Bulk endpoints may also be used
+ * for interrupt transfers; but the reverse is not true, and some endpoints
+ * won't support every interrupt transfer.  (Such as 768 byte packets.)
+ *
+ * Interrupt-only endpoints are less functional than bulk endpoints, for
+ * example by not supporting queueing or not handling buffers that are
+ * larger than the endpoint's maxpacket size.  They may also treat data
+ * toggle differently.
+ *
+ * Control endpoints ... after getting a setup() callback, the driver queues
+ * one response (even if it would be zero length).  That enables the
+ * status ack, after transfering data as specified in the response.  Setup
+ * functions may return negative error codes to generate protocol stalls.
+ * (Note that some USB device controllers disallow protocol stall responses
+ * in some cases.)  When control responses are deferred (the response is

+/**
+ * struct usb_gadget_driver - driver for usb 'slave' devices
+ * @function: String describing the gadget's function
+ * @speed: Highest speed the driver handles.
+ * @bind: Invoked when the driver is bound to a gadget, usually
+ *      after registering the driver.
+ *      At that point, ep0 is fully initialized, and ep_list holds
+ *      the currently-available endpoints.
+ *      Called in a context that permits sleeping.
+ * @setup: Invoked for ep0 control requests that aren't handled by
+ *      the hardware level driver. Most calls must be handled by
+ *      the gadget driver, including descriptor and configuration
+ *      management.  The 16 bit members of the setup data are in
+ *      cpu order. Called in_interrupt; this may not sleep.  Driver
+ *      queues a response to ep0, or returns negative to stall.
+ * @disconnect: Invoked after all transfers have been stopped,
+ *      when the host is disconnected.  May be called in_interrupt; this
+ *      may not sleep.  Some devices can't detect disconnect, so this might
+ *      not be called except as part of controller shutdown.
+ * @unbind: Invoked when the driver is unbound from a gadget,
+ *      usually from rmmod (after a disconnect is reported).
+ *      Called in a context that permits sleeping.
+ * @suspend: Invoked on USB suspend.  May be called in_interrupt.
+ * @resume: Invoked on USB resume.  May be called in_interrupt.
+ * @driver: Driver model state for this driver.
+ *
+ * Devices are disabled till a gadget driver successfully bind()s, which
+ * means the driver will handle setup() requests needed to enumerate (and
+ * meet "chapter 9" requirements) then do some useful work.
+ *
+ * If gadget->is_otg is true, the gadget driver must provide an OTG
+ * descriptor during enumeration, or else fail the bind() call.  In such
+ * cases, no USB traffic may flow until both bind() returns without
+ * having called usb_gadget_disconnect(), and the USB host stack has
+ * initialized.
+ *
+ * Drivers use hardware-specific knowledge to configure the usb hardware.
+ * endpoint addressing is only one of several hardware characteristics that
+ * are in descriptors the ep0 implementation returns from setup() calls.
+ *
+ * Except for ep0 implementation, most driver code shouldn't need change to
+ * run on top of different usb controllers.  It'll use endpoints set up by
+ * that ep0 implementation.
+ *
+ * The usb controller driver handles a few standard usb requests.  Those
+ * include set_address, and feature flags for devices, interfaces, and
+ * endpoints (the get_status, set_feature, and clear_feature requests).
+ *
+ * Accordingly, the driver's setup() callback must always implement all
+ * get_descriptor requests, returning at least a device descriptor and
+ * a configuration descriptor.  Drivers must make sure the endpoint
+ * descriptors match any hardware constraints. Some hardware also constrains
+ * other descriptors. (The pxa250 allows only configurations 1, 2, or 3).
+ *
+ * The driver's setup() callback must also implement set_configuration,
+ * and should also implement set_interface, get_configuration, and
+ * get_interface.  Setting a configuration (or interface) is where
+ * endpoints should be activated or (config 0) shut down.
+ *
+ * (Note that only the default control endpoint is supported.  Neither
+ * hosts nor devices generally support control traffic except to ep0.)
+ *
+ * Most devices will ignore USB suspend/resume operations, and so will
+ * not provide those callbacks.  However, some may need to change modes
+ * when the host is not longer directing those activities.  For example,
+ * local controls (buttons, dials, etc) may need to be re-enabled since
+ * the (remote) host can't do that any longer; or an error state might
+ * be cleared, to make the device behave identically whether or not
+ * power is maintained.

+/*
+ * Initial APIs (1996 -> onward) :
+ * -----------------------------
+ * Basically, the wireless extensions are for now a set of standard ioctl
+ * call + /proc/net/wireless
+ *
+ * The entry /proc/net/wireless give statistics and information on the
+ * driver.
+ * This is better than having each driver having its entry because
+ * its centralised and we may remove the driver module safely.
+ *
+ * Ioctl are used to configure the driver and issue commands.  This is
+ * better than command line options of insmod because we may want to
+ * change dynamically (while the driver is running) some parameters.
+ *
+ * The ioctl mechanimsm are copied from standard devices ioctl.
+ * We have the list of command plus a structure descibing the
+ * data exchanged...
+ * Note that to add these ioctl, I was obliged to modify :
+ *      # net/core/dev.c (two place + add include)
+ *      # net/ipv4/af_inet.c (one place + add include)
+ *
+ * /proc/net/wireless is a copy of /proc/net/dev.
+ * We have a structure for data passed from the driver to /proc/net/wireless
+ * Too add this, I've modified :
+ *      # net/core/dev.c (two other places)
+ *      # include/linux/netdevice.h (one place)
+ *      # include/linux/proc_fs.h (one place)
+ *
+ * New driver API (2002 -> onward) :
+ * -------------------------------
+ * This file is only concerned with the user space API and common definitions.
+ * The new driver API is defined and documented in :
+ *      # include/net/iw_handler.h
+ *
+ * Note as well that /proc/net/wireless implementation has now moved in :
+ *      # net/core/wireless.c
+ *
+ * Wireless Events (2002 -> onward) :
+ * --------------------------------
+ * Events are defined at the end of this file, and implemented in :
+ *      # net/core/wireless.c
+ *
+ * Other comments :
+ * --------------
+ * Do not add here things that are redundant with other mechanisms
+ * (drivers init, ifconfig, /proc/net/dev, ...) and with are not
+ * wireless specific.
+ *
+ * These wireless extensions are not magic : each driver has to provide
+ * support for them...
+ *
+ * IMPORTANT NOTE : As everything in the kernel, this is very much a
+ * work in progress. Contact me if you have ideas of improvements...

+/*
+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may introduce some
+  output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows. deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly. This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).
+    Some output may be provided even if flush is not set.
+
+  Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating avail_in or avail_out accordingly; avail_out
+  should never be zero before the call. The application can consume the
+  compressed output when it wants, for example when the output buffer is full
+  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+  and with zero avail_out, it must be called again after making room in the
+  output buffer because there might be more output pending.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far. (In particular
+  avail_in is zero after the call if enough output space has been provided
+  before the call.)  Flushing may degrade compression for some compression
+  algorithms and so it should be used only when necessary.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+  the compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there
+  was enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no
+  more input data, until it returns with Z_STREAM_END or an error. After
+  deflate has returned Z_STREAM_END, the only possible operations on the
+  stream are deflateReset or deflateEnd.
+  
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step. In this case, avail_out must be at least
+  0.1% larger than avail_in plus 12 bytes.  If deflate does not return
+  Z_STREAM_END, then it must be called again as described above.
+
+    deflate() sets strm->adler to the adler32 checksum of all input read
+  so far (that is, total_in bytes).
+
+    deflate() may update data_type if it can make a good guess about
+  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
+  binary. This field is only for information purposes and does not affect
+  the compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example

+
+extern int zlib_inflate (z_streamp strm, int flush);
+/*
+    inflate decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may some
+  introduce some output latency (reading input without producing any output)
+  except when forced to flush.
+
+  The detailed semantics are as follows. inflate performs one or both of the
+  following actions:
+
+  - Decompress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in is updated and processing
+    will resume at this point for the next call of inflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() provides as much output as possible, until there
+    is no more input data or no more space in the output buffer (see below
+    about the flush parameter).
+
+  Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating the next_* and avail_* values accordingly.
+  The application can consume the uncompressed output when it wants, for
+  example when the output buffer is full (avail_out == 0), or after each
+  call of inflate(). If inflate returns Z_OK and with zero avail_out, it
+  must be called again after making room in the output buffer because there
+  might be more output pending.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
+  output as possible to the output buffer. The flushing behavior of inflate is
+  not specified for values of the flush parameter other than Z_SYNC_FLUSH
+  and Z_FINISH, but the current implementation actually flushes as much output
+  as possible anyway.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error. However if all decompression is to be performed in a single step
+  (a single call of inflate), the parameter flush should be set to
+  Z_FINISH. In this case all pending input is processed and all pending
+  output is flushed; avail_out must be large enough to hold all the
+  uncompressed data. (The size of the uncompressed data may have been saved
+  by the compressor for this purpose.) The next operation on this stream must
+  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
+  is never required, but can be used to inform inflate that a faster routine
+  may be used for the single inflate() call.
+
+     If a preset dictionary is needed at this point (see inflateSetDictionary
+  below), inflate sets strm-adler to the adler32 checksum of the
+  dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise 
+  it sets strm->adler to the adler32 checksum of all output produced
+  so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or
+  an error code as described below. At the end of the stream, inflate()
+  checks that its computed adler32 checksum is equal to that saved by the
+  compressor and returns Z_STREAM_END only if the checksum is correct.
+
+    inflate() returns Z_OK if some progress has been made (more input processed
+  or more output produced), Z_STREAM_END if the end of the compressed data has
+  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect
+  adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent
+  (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not
+  enough memory, Z_BUF_ERROR if no progress is possible or if there was not
+  enough room in the output buffer when Z_FINISH is used. In the Z_DATA_ERROR
+  case, the application may then call inflateSync to look for a good
+  compression block.

+
+     This is another version of deflateInit with more compression options. The
+   fields next_in, zalloc, zfree and opaque must be initialized before by
+   the caller.
+
+     The method parameter is the compression method. It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library. Larger values of this parameter result in better
+   compression at the expense of memory usage. The default value is 15 if
+   deflateInit is used instead.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state. memLevel=1 uses minimum memory but
+   is slow and reduces compression ratio; memLevel=9 uses maximum memory
+   for optimal speed. The default value is 8. See zconf.h for total memory
+   usage as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm. Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match).  Filtered data consists mostly of small values with a
+   somewhat random distribution. In this case, the compression algorithm is
+   tuned to compress them better. The effect of Z_FILTERED is to force more
+   Huffman coding and less string matching; it is somewhat intermediate
+   between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
+   the compression ratio but not the correctness of the compressed output even
+   if it is not set appropriately.
+
+      deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+   memory, Z_STREAM_ERROR if a parameter is invalid (such as an invalid
