Pull userns updates from Eric Biederman:
 "Between the holidays and other distractions only a small amount of
  namespace work made it into my tree this time.

  Just a final cleanup from a revert several kernels ago and a small
  typo fix from Wolffhardt Schwabe"

* 'userns-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
  fix typo in assignment of fs default overflow gid
  autofs4: Modify autofs_wait to use current_uid() and current_gid()
  userns: Don't fail follow_automount based on s_user_ns
