[Al Viro <viro@ZenIV.linux.org.uk>]

	Several fixes + obvious cleanup (you've missed a couple of
open-coded can_lookup() back then).  Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus

Shortlog:
Al Viro (2):
      use can_lookup() instead of direct checks of ->i_op->lookup
      snd_pcm_link(): fix a leak...

Dave Chiluk (1):
      ncpfs: fix rmdir returns Device or resource busy

Oleg Nesterov (2):
      fput: task_work_add() can fail if the caller has passed exit_task_work()
      move exit_task_namespaces() outside of exit_notify()
