[PATCH v2 5/5] blk-mq: Enable support for runtime power management

From: Bart Van Assche <hidden>
Date: 2018-07-25 23:39:54
Subsystem: block layer, the rest · Maintainers: Jens Axboe, Linus Torvalds

Now that the blk-mq core processes power management requests
(marked with RQF_PREEMPT) in other states than RPM_ACTIVE, enable
runtime power management for blk-mq.
