I'll assume that also means that applying the patch is reasonable.

In our case we aren't using raid5; how ever we are using raid to mirror
two root partitions. Your explanation to Andrew indicates the problem
should only occur when using raid5. So applying the patch should be only
have the effect of making it now possible to use raid5 with dm-crypt.
Since we are currently running raid with root encryption it feels like
it's better to include your patch.
