	More fixes for the stuff that went in during the merge window...
I've dropped the get_net_ns_by_fd fix from this queue, since davem has taken
it in net-2.6.git.  Please, pull from usual place -
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ #for-linus

Shortlog:
Al Viro (1):
      more conservative S_NOSEC handling

Assorted bug fixes (probably all of that should be -stable fodder, with
the exception of kmemleak cosmetical one).  The usual place,

      coda: deal correctly with allocation failure from coda_cnode_makectl()
      coda: switch coda_cnode_make() to sane API as well, clean coda_lookup()
      hfsplus: creation of hidden dir on mount can fail
      autofs4: autofs4_wait() vs. autofs4_catatonic_mode() race
      autofs4: catatonic_mode vs. notify_daemon race
      autofs4: deal with autofs4_write/autofs4_write races

	Several fixes for Nick's RCU stuff; open() without O_CREAT
can be tricked into creating files, ->d_compare() in /proc/sys is trying
and failing to be RCU-safe (strictly speaking not a regression, but only
because it will be kicked out of RCU mode by ->permission() refusing
to accept IPERM_FLAG_RCU) and spurious errors in open() and vfs_path_lookup()
since we forget to set nd->inode on the LOOKUP_REVAL attempt.  More fixes
tomorrow...  Please, pull from

git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ for-linus

Shortlog:
Al Viro (3):
      minimal fix for do_filp_open() race
      unfuck proc_sysctl ->d_compare()
      nd->inode is not set on the second attempt in path_walk()

Sanitized locking for ->mnt_expiry, race fixes for shrink_submounts(),
some stack footprint reduction on using struct path instead of struct
nameidata in several places in namespace.c (more will be possible once
we sanitize prototypes of several LSM hooks, but that's post-25).

Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ for-linus

Shortlog:
Al Viro (5):
      reduce stack footprint in namespace.c
      count ghost references to vfsmounts
      sanitize locking in mark_mounts_for_expiry() and shrink_submounts()
      do shrink_submounts() for all fs types
      mnt_expire is protected by namespace_sem, no need for vfsmount_lock
