H A Dblk-mq-sched.c7d7ca7c5 Thu Aug 27 21:52:56 CDT 2020 Baolin Wang <baolin.wang@linux.alibaba.com> block: Add a new helper to attempt to merge a bio

There are lots of duplicated code when trying to merge a bio from
plug list and sw queue, we can introduce a new helper to attempt
to merge a bio, which can simplify the blk_bio_list_merge()
and blk_attempt_plug_merge().
