If a raid5/6 reshape is restarted (After stopping and re-assembling
the array) and the array is marked read-only (or read-auto), then
the reshape will appear to complete immediately, without actually
moving anything around. This can result in corruption.
There are two patches which do much the same thing in different places.
They are separate because one is an older bug and so can be applied to
more -stable kernels.

"Two md bugfixes for possible corruption when restarting reshape
If a raid5/6 reshape is restarted (After stopping and re-assembling
the array) and the array is marked read-only (or read-auto), then the
reshape will appear to complete immediately, without actually moving
anything around. This can result in corruption.

* tag 'md/3.15-fixes' of git://neil.brown.name/md:
md: always set MD_RECOVERY_INTR when interrupting a reshape thread.
md: always set MD_RECOVERY_INTR when aborting a reshape or other "resync".
