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

Pull pile 2 of vfs updates from Al Viro:
 "Stuff in this one - assorted fixes, lglock tidy-up, death to
  lock_super().

  There'll be a VFS pile tomorrow (with patches from Jeff Layton,
  sanitizing getname() and related parts of audit and preparing for
  ESTALE fixes), but I'd rather push the stuff in this one ASAP - some
  of the bugs closed here are quite unpleasant."
