Subject: [PATCH 0/5] Some clean-ups for bio merge

Hi,

There are some duplicated code when trying to merge bio from pluged list
and software queue, thus this patch set did some clean-ups when merging
a bio. Any comments are welcome. Thanks.

Baolin Wang (5):
  block: Move bio merge related functions into blk-merge.c
  block: Remove redundant blk_mq_sched_allow_merge() validation
  block: Add a new helper to attempt to merge a bio
  block: Remove blk_mq_attempt_merge() function
  block: Remove __blk_mq_sched_bio_merge() helper
