I can't say, that's not under my control.

The reason I'm reluctant is that the code being patched is different in
2.6.32, split out into separate functions for raid5 and raid6. While the
backport looks straightforward I'd really prefer that someone was able
to test it, and I don't have any machines at my disposal with enough
disks to set up raid5/6.
