+ * struct export_operations - for nfsd to communicate with file systems
+ * @decode_fh:      decode a file handle fragment and return a &struct dentry
+ * @encode_fh:      encode a file handle fragment from a dentry
+ * @get_name:       find the name for a given inode in a given directory
+ * @get_parent:     find the parent of a given directory
+ * @get_dentry:     find a dentry for the inode given a file handle sub-fragment
+ * @find_exported_dentry:
+ *      set by the exporting module to a standard helper function.
+ *
+ * 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_mutex 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_mutex down
+ *    get_name is not (which is possibly inconsistent)

-/**
- * struct export_operations - for nfsd to communicate with file systems
- * @decode_fh:      decode a file handle fragment and return a &struct dentry
- * @encode_fh:      encode a file handle fragment from a dentry
- * @get_name:       find the name for a given inode in a given directory
- * @get_parent:     find the parent of a given directory
- * @get_dentry:     find a dentry for the inode given a file handle sub-fragment
- * @find_exported_dentry:
- *      set by the exporting module to a standard helper function.
- *
- * 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_mutex 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_mutex down
- *    get_name is not (which is possibly inconsistent)

+
+/* Some rough guidelines on accessing and updating grant-table entries
+ * in a concurrency-safe manner. For more information, Linux contains a
+ * reference implementation for guest OSes (arch/xen/kernel/grant_table.c).
+ *
+ * NB. WMB is a no-op on current-generation x86 processors. However, a
+ *     compiler barrier will still be required.
+ *
+ * Introducing a valid entry into the grant table:
+ *  1. Write ent->domid.
+ *  2. Write ent->frame:
+ *      GTF_permit_access:   Frame to which access is permitted.
+ *      GTF_accept_transfer: Pseudo-phys frame slot being filled by new
+ *                           frame, or zero if none.
+ *  3. Write memory barrier (WMB).
+ *  4. Write ent->flags, inc. valid type.
+ *
+ * Invalidating an unused GTF_permit_access entry:
+ *  1. flags = ent->flags.
+ *  2. Observe that !(flags & (GTF_reading|GTF_writing)).
+ *  3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
+ *  NB. No need for WMB as reuse of entry is control-dependent on success of
+ *      step 3, and all architectures guarantee ordering of ctrl-dep writes.
+ *
+ * Invalidating an in-use GTF_permit_access entry:
+ *  This cannot be done directly. Request assistance from the domain controller
+ *  which can set a timeout on the use of a grant entry and take necessary
+ *  action. (NB. This is not yet implemented!).
+ *
+ * Invalidating an unused GTF_accept_transfer entry:
+ *  1. flags = ent->flags.
+ *  2. Observe that !(flags & GTF_transfer_committed). [*]
+ *  3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
+ *  NB. No need for WMB as reuse of entry is control-dependent on success of
+ *      step 3, and all architectures guarantee ordering of ctrl-dep writes.
+ *  [*] If GTF_transfer_committed is set then the grant entry is 'committed'.
+ *      The guest must /not/ modify the grant entry until the address of the
+ *      transferred frame is written. It is safe for the guest to spin waiting
+ *      for this to occur (detect by observing GTF_transfer_completed in
+ *      ent->flags).
+ *
+ * Invalidating a committed GTF_accept_transfer entry:
+ *  1. Wait for (ent->flags & GTF_transfer_completed).
+ *
+ * Changing a GTF_permit_access from writable to read-only:
+ *  Use SMP-safe CMPXCHG to set GTF_readonly, while checking !GTF_writing.
+ *
+ * Changing a GTF_permit_access from read-only to writable:
+ *  Use SMP-safe bit-setting instruction.

+         *     such as xenstore).
+         *  2. Physical interrupts. A domain with suitable hardware-access
+         *     privileges can bind an event-channel port to a physical interrupt
+         *     source.
+         *  3. Virtual interrupts ('events'). A domain can bind an event-channel
+         *     port to a virtual interrupt source, such as the virtual-timer
+         *     device or the emergency console.
+         *
+         * Event channels are addressed by a "port index". Each channel is
+         * associated with two bits of information:
+         *  1. PENDING -- notifies the domain that there is a pending notification
+         *     to be processed. This bit is cleared by the guest.
+         *  2. MASK -- if this bit is clear then a 0->1 transition of PENDING
+         *     will cause an asynchronous upcall to be scheduled. This bit is only
+         *     updated by the guest. It is read-only within Xen. If a channel
+         *     becomes pending while the channel is masked then the 'edge' is lost

+         *     pending notifications as no upcall will be scheduled by Xen).

+         * To expedite scanning of pending notifications, any 0->1 pending
+         * transition on an unmasked channel causes a corresponding bit in a

+ * we are foreign-mapping the MFN, and the other domain as m2p(MFN) == PFN.
+ * Yikes! Various places must poke in INVALID_P2M_ENTRY for safety.
