Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4

Pull ext4 regression fixes from Ted Ts'o:
 "This fixes a scalability problem reported by Andi Kleen and Tim Chen;
  they were quite secretive about the precise nature of their workload,
  but they later admitted that it only showed up when they were using a
  large sparse file, so the amount of data I/O that was needed was close
  to zero.

  I'm not sure how realistic this is and it's only a regression if you
  consider changes made since 2.6.39 to be a "regression" vis-a-vis the
  policy regarding post-merge window bug fixes, but Linus agreed it was
  worth fixing, so I'm including it in this pull request.

  This also fixes the journalled quota mount options, which I
  accidentally broke while I was cleaning up the mount option handling."
