[Bug 1364091] Re: Possible RAID-6 corruption

[swmike]

This problem affects all stable kernels from 2.6.32 and onwards, and
this patch needs to be applied to ALL kernels from that date to avoid
data corruption on double degraded RAID-6 volumes being written to.

This is not an mdadm problem, it's a kernel problem.
