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.

I was not sure if or how much or where people wanted to stick things.
There also appears to be room in the bi_flags field. If bi_flags is
only using 13 bits and there are only 16 REQ_XYZs bits related bios,
I could put them all in one variable if we wanted to go wild with trying
to shrink the bio while I am at it..

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