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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
