  md/raid1,raid10: don't compare excess byte during consistency check. (2012-04-03 15:39:23 +1000)

----------------------------------------------------------------
md: Assort fixes for 3.4-rc

- some RAID levels didn't clear up properly if md_integrity_register
  failed
- a 'check' of RAID5/RAID6 doesn't actually read any data
  since a recent patch - so fix that (and mark for -stable)
- a couple of other minor bugs.

----------------------------------------------------------------

      md: Avoid OOPS when reshaping raid1 to raid0
