[PATCH 3/5] null_blk: use __blk_mq_complete_request in timeout path

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

 



To regain the capability to prevent normal completion path from
entering a timeout request, blk_mq_mark_rq_complete is introduced
in blk_mq_complete_request. Have to use __blk_mq_complete_request
in timeout path to complete a timeout request.
