From: Al Viro
Date: Tue Oct 02 2012 - 21:39:47 EST

This is *not* all; fs/dcache.c bits will go separately, for one
thing - that's just the first pile. Please, pull from the usual place -
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus
Shortlog:
Al Viro (67):
do_add_mount()/umount -l races
close the race in nlmsvc_free_block()
Merge remote branch 'origin' into for-next
take descriptor handling from sock_alloc_file() to callers
unexport sock_map_fd(), switch to sock_alloc_file()
make get_unused_fd_flags() a function
autofs4: don't open-code fd_install()
binder: don't allow mmap() by process other than proc->tsk
pipe(2) - race-free error recovery
events: don't use get_unused_fd_flags() when get_unused_fd() will do
fanotify: sanitize failure exits in copy_event_to_user()
take rlimit check to callers of expand_files()
new helper: __alloc_fd()
move files_struct-related bits from kernel/exit.c to fs/file.c
don't bother with call_rcu() in put_files_struct()
trim free_fdtable_rcu()
move put_unused_fd() and fd_install() to fs/file.c
expose a low-level variant of fd_install() for binder
take fget() and friends to fs/file.c
take descriptor-related part of close() to file.c
um: resurrect the right variant of mconsole_proc()
take close-on-exec logics to fs/file.c, clean it up a bit
take purely descriptor-related stuff from fcntl.c to file.c
new helper: replace_fd()
switch flush_unauthorized_files() to replace_fd()
take __{set,clear}_{open_fd,close_on_exec}() into fs/file.c
make expand_files() and alloc_fd() static
new helper: iterate_fd()

switch SNDRV_PCM_IOCTL_LINK to fget_light()
switch mqueue syscalls to fget_light()
switch btrfs_ioctl_clone() to fget_light()
switch vfio_group_set_container() to fget_light()
switch infinibarf users of fget() to fget_light()
switch coda get_device_index() to fget_light()
switch xfs_swapext() to fget_light()
switch xfs_find_handle() to fget_light()
switch prctl_set_mm_exe_file() to fget_light()
vhost_set_vring(): turn pollstart/pollstop into bool
make get_file() return its argument
proc_map_files_readdir(): don't bother with grabbing files
switch o2hb_region_dev_write() to fget_light()
new helpers: fdget()/fdput()
switch simple cases of fget_light to fdget
hypfs: ->d_parent is never NULL or negative
ceph: don't abuse d_delete() on failure exits
fcntl: fix misannotations
usb/gadget: fix misannotations
btrfs: reada_extent doesn't need kref for refcount
