[PATCH 0/2] Use MD_BROKEN for redundant arrays

[Mariusz Tkaczyk]

Hi Song,
This patchset adds usage of MD_BROKEN for each redundant level.
This should simplify IO failure stack when md device is failed and
fixes raid456 bug.

Mariusz Tkaczyk (2):
  md: Set MD_BROKEN for RAID1 and RAID10
  raid5: introduce MD_BROKEN
