Subject: [PATCH v3 1/5] blk-mq: introduce blk_mq_set_request_complete
Date: Thu, 21 Jan 2021 15:03:26 +0800 [thread overview]
Message-ID: <20210121070330.19701-2-lengchao@huawei.com> (raw)
In-Reply-To: <20210121070330.19701-1-lengchao@huawei.com>
nvme drivers need to set the state of request to MQ_RQ_COMPLETE when
directly complete request in queue_rq.
So add blk_mq_set_request_complete.
