I was going to ask about splitting it, but that looks fine, I can pull
that in.
The series looks fine to me. My only real concern is giving drivers the
flexibility to define mappings, I don't want that to evolve into drivers
(again) doing stupid things wrt mappings. As long as we keep it strictly
as a tunnel for passing mappings defined by the (previous blk-mq) core
code, then that's fine.
