Subject: Re: [PATCH 32/32] block: remove __REQ op defs and reduce bi_op/bi_rw sizes

I love this series!

Also I think it's very good that we finally split the ioprio out to it's
own field.

Thanks a lot for doing this work.

This sounds interesting, but I'd rather do it as a separate project
later.
