Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull vfs fixes from Al Viro:
 "dcache fixes + kvfree() (uninlined, exported by mm/util.c) + posix_acl
  bugfix from hch"

The dcache fixes are for a subtle LRU list corruption bug reported by
Miklos Szeredi, where people inside IBM saw list corruptions with the
LTP/host01 test.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  nick kvfree() from apparmor
  posix_acl: handle NULL ACL in posix_acl_equiv_mode
  dcache: don't need rcu in shrink_dentry_list()
  more graceful recovery in umount_collect()
  don't remove from shrink list in select_collect()
  dentry_kill(): don't try to remove from shrink list
  expand the call of dentry_lru_del() in dentry_kill()
  new helper: dentry_free()
  fold try_prune_one_dentry()
  fold d_kill() and d_free()
  fix races between __d_instantiate() and checks of dentry flags
