Hi Jens
The 1st patch refactors the code of issue request directly. It merges the blk_mq_try_issue_directly and __blk_mq_try_issue_directly and make blk_mq_try_issue_directly handle return value of .queue_rq itself.
The 2nd patch make blk_mq_sched_insert_requests issue request directly with bypass "false" instead of the "true", then needn't to handle the non-issued requests any more.
The 3rd patch ensures the hctx to be ran on its mapped cpu in issue directly path.
V2: - Add 1st and 2nd patch.
