This is basically identical to deadline-iosched, except it registers
as a MQ capable scheduler. This is still a single queue design.

One last question (for today ...):in mq-deadline there are no
"schedule dispatch" or "unplug work" functions.  In blk, CFQ and BFQ
do these schedules/unplugs in a lot of cases.  What's the right
replacement?  Just doing nothing?

You just use blk_mq_run_hw_queue() or variants thereof to kick off queue
runs.
