* Remove rcu_assign_pointer() penalty for NULL pointersPaul E. McKenney2008-02-06
| | | | | | | | | | | | | | | | | | | | | The rcu_assign_pointer() primitive currently unconditionally executes a memory barrier, even when a NULL pointer is being assigned. This has lead some to avoid using rcu_assign_pointer() for NULL pointers, which loses the self-documenting advantages of rcu_assign_pointer() This patch uses __builtin_const_p() to omit needless memory barriers for NULL-pointer assignments at compile time with no runtime penalty, as discussed in the following thread: http://www.mail-archive.com/netdev@vger.kernel.org/msg54852.html Tested on x86_64 and ppc64, also compiled the four cases (NULL/non-NULL and const/non-const) with gcc version 4.1.2, and hand-checked the assembly output.

* Fix __const_udelay declaration and definition mismatchesJeff Dike2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The declaration and implementation of __const_udelay use different names for the parameter on a number of architectures: include/asm-avr32/delay.h:15:extern void __const_udelay(unsigned long usecs); arch/avr32/lib/delay.c:39:inline void __const_udelay(unsigned long xloops) include/asm-sh/delay.h:15:extern void __const_udelay(unsigned long usecs); arch/sh/lib/delay.c:22:inline void __const_udelay(unsigned long xloops) include/asm-m32r/delay.h:15:extern void __const_udelay(unsigned long usecs); arch/m32r/lib/delay.c:58:void __const_udelay(unsigned long xloops) include/asm-x86/delay.h:16:extern void __const_udelay(unsigned long usecs); arch/x86/lib/delay_32.c:82:inline void __const_udelay(unsigned long xloops) arch/x86/lib/delay_64.c:46:inline void __const_udelay(unsigned long xloops) The units of the parameter isn't usecs, so that name is definitely wrong. It's also not exactly loops, so I suppose xloops is an OK name. This patch changes these names from usecs to xloops.

* get rid of NR_OPEN and introduce a sysctl_nr_openEric Dumazet2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | NR_OPEN (historically set to 1024*1024) actually forbids processes to open more than 1024*1024 handles. Unfortunatly some production servers hit the not so 'ridiculously high value' of 1024*1024 file descriptors per process. Changing NR_OPEN is not considered safe because of vmalloc space potential exhaust. This patch introduces a new sysctl (/proc/sys/fs/nr_open) wich defaults to 1024*1024, so that admins can decide to change this limit if their workload needs it.

* inotify: send IN_ATTRIB events when link count changesJan Kara2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, no notification event has been sent when inode's link count changed. This is inconvenient for the application in some cases: Suppose you have the following directory structure foo/test bar/ and you watch test. If someone does "mv foo/test bar/", you get event IN_MOVE_SELF and you know something has happened with the file "test". However if someone does "ln foo/test bar/test" and "rm foo/test" you get no inotify event for the file "test" (only directories "foo" and "bar" receive events). Furthermore it could be argued that link count belongs to file's metadata and thus IN_ATTRIB should be sent when it changes. The following patch implements sending of IN_ATTRIB inotify events when link count of the inode changes, i.e., when a hardlink to the inode is created or when it is removed. This event is sent in addition to all the events sent so far. In particular, when a last link to a file is removed, IN_ATTRIB event is sent in addition to IN_DELETE_SELF event.

| | | | | | | | | | | | | | | | | The clean up procedure now uses platform device "release" callback to handle memory clean up.

* smbfs: fix calculation of kernel_recvmsg size parameter in smb_receive()Jeff Layton2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | smb_receive calls kernel_recvmsg with a size that's the minimum of the amount of buffer space in the kvec passed in or req->rq_rlen (which represents the length of the response). This does not take into account any data that was read in a request earlier pass through smb_receive. If the first pass through smb_receive receives some but not all of the response, then the next pass can call kernel_recvmsg with a size field that's too big. kernel_recvmsg can overrun into the next response, throwing off the alignment and making it unrecognizable. This causes messages like this to pop up in the ring buffer: smb_get_length: Invalid NBT packet, code=69 as well as other errors indicating that the response is unrecognizable. Typically this is seen on a smbfs mount under heavy I/O. This patch changes the code to use (req->rq_rlen - req->rq_bytes_recvd) instead instead of just req->rq_rlen, since that should represent the amount of unread data in the response. I think this is correct, but an ACK or NACK from someone more familiar with this code would be appreciated...

| | | | | | | | | | | | | | | | | | | | - All implementations can be __devinit - The function prototypes were in asm/timex.h but they all must be the same, so create a single declaration in linux/timex.h. - uninline the sparc64 version to match the other architectures - Don't bother #defining ARCH_HAS_READ_CURRENT_TIMER to a particular value.

* MNT_UNBINDABLE fixAndries E. Brouwer2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some time ago ( http://lkml.org/lkml/2007/6/19/128 ) I wrote about MNT_UNBINDABLE that it felt like a bug that it is not reset by "mount --make-private". Today I happened to see mount(8) and Documentation/sharedsubtree.txt and both document the version obtained by applying the little patch given in the above (and again below). So, the present kernel code is not according to specs and must be regarded as buggy. Specification in Documentation/sharedsubtree.txt: See state diagram: unbindable should become private upon make-private. Specification in mount(8): ... It's also possible to set up uni-directional propagation (with --make- slave), to make a mount point unavailable for --bind/--rbind (with --make-unbindable), and to undo any of these (with --make-private).
