Do you suspect that btrfs will also want to perform these operations
asynchronously?  I am preparing an updated release of the raid6
offload patch kit, but the previous WIP release can be browsed at:

http://git.kernel.org/?p=linux/kernel/git/djbw/async_tx.git;a=shortlog;h=raid6

The routines are housed in crypto/async_tx/async_pq.c and
crypto/async_tx/async_raid6_recov.c.

I also wonder if the raid6 algos are a better fit under crypto/ alongside xor?
