I don't like the per-driver switch as module_parameter at all and we should never do that. We had some exceptions for drivers to force blk_mq (e.g. virtio), and given that I don't think we'll solve the blk-mq runtime-pm issue for 4.19 and also don't want to revert the default I think this patch is the best compromise for 4.19, with a revert in 4.20 once we have runtime-pm for blk-mq.
So:
