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

Pull vfs fixes from Al Viro:
 "MS_I_VERSION fixes - Mimi's fix + missing bits picked from Matthew
  (his patch contained a duplicate of the fs/namespace.c fix as well,
  but by that point the original fix had already been applied)"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  Convert fs/*/* to SB_I_VERSION
  vfs: fix mounting a filesystem with i_version
