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

Pull VFS patches (part 1) from Al Viro:
 "The major change in this pile is ->readdir() replacement with
  ->iterate(), dealing with ->f_pos races in ->readdir() instances for
  good.

  There's a lot more, but I'd prefer to split the pull request into
  several stages and this is the first obvious cutoff point."
