While I like the idea of centralizing stuff like this, I'm also not
happy with adding checks like this to the fast path. But I guess it's
still better than stuff it in drivers.
You have an extra line after both of these above hunks for some reason.
Can you clean that up?
And the blk-mq.c hunk, we have 'q' in that function, use that instead of
rq->q.
