This patch fixes a bug in the XOR driver where the cleanup function can be
called and free descriptors that never been processed by the engine (which
result in data errors).

The cleanup function will free descriptors based on the ownership bit in
the descriptors.

If this is fixing a bug, shouldn't it be Cc'ed to stable@ ? But then it
needs to be the first patch in the series.

From what I remember, this series both fixes some issues *and* adds

RAID6 support. We need to separate out the two things so that the fixes
can be propagated to stable.

Thanks,

Thomas
