+Hi all,
+ There is a risk of data loss with md/raid6 arrays running on Linux since
+ 2.6.32.
+ If:
+   - the array is doubly degraded
+   - one or both failed devices are being recovered, and
+   - the array is written to
+
+ then it is possible for data on the array to be lost.  The patch below fixes
+ the problem.  If you apply the patch to an older kernel which has separate
+ handle_stripe5() and handle_stripe6() functions, be sure that patch changes
+ handle_stripe6().
+
+ There is no risk to an optimal array or a singly-degraded array.  There is
+ also no risk on a doubly-degraded array which is not recovering a device or
+ is not receiving write requests.
+
+ If you have data on a RAID6 array, please consider how to avoid corruption,
+ possibly by applying the patch, possibly by removing any hot spares so
+ recovery does not automatically start.
+
+ This patch will be sent upstream shortly and will subsequently appear in
+ future "-stable" kernels.

+Subject: [PATCH] md/raid6: avoid data corruption during recovery of
+ double-degraded RAID6
+
+During recovery of a double-degraded RAID6 it is possible for
+some blocks not to be recovered properly, leading to corruption.
+
+If a write happens to one block in a stripe that would be written to a
+missing device, and at the same time that stripe is recovering data
+to the other missing device, then that recovered data may not be written.
+
+This patch skips, in the double-degraded case, an optimisation that is
+only safe for single-degraded arrays.
+
+Bug was introduced in 2.6.32 and fix is suitable for any kernel since
+then.  In an older kernel with separate handle_stripe5() and
+handle_stripe6() functions that patch must change handle_stripe6().
