Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull vfs fixes from Al Viro:
 "MS_MOVE regression fix + breakage in fsmount(2) (also introduced in
  this cycle, along with fsmount(2) itself).

  I'm still digging through the piles of mail, so there might be more
  fixes to follow, but these two are obvious and self-contained, so
  there's no point delaying those..."
