Modify the raid6 driver to offload stripe operations to the async_tx api.
git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx.git raid6
The changes since v1 are:
1/ Use a percpu scribble buffer for passing the address lists and a
raid6 spare page to the async_tx api.
2/ Fixed a potential assertion in handle_parity_checks6()
3/ An experimental multicore raid456 option. Given the new percpu
scheme it is a straightforward conversion to have raid5d issue
work to the async thread pool.
As before let me know if it is suitable to take this into linux-next via
async_tx.git/next, or if you would rather it go through md.git/for-next.
Thanks,
Dan
