Xiao Ni 23f3e3272e block: Merge bio before checking ->cached_rq ... It checks if plug->cached_rq is empty before merging bio. But the merge action doesn't have relationship with plug->cached_rq, it trys to merge bio with requests within plug->mq_list. Now it checks if ->cached_rq is empty before merging bio. If it's empty, it will miss the merge chances. So move the merge function before checking ->cached_rq.
