Subject: [PATCH v2 0/3] 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.

Changes from v1:
 - Drop patch 2 and patch 5 in v1 patch set.
 - Add reviewed-by tag from Christoph.
 - Move blk_mq_bio_list_merge() into blk-merge.c and rename it.
 - Some coding style improvements.

Baolin Wang (3):
  block: Move bio merge related functions into blk-merge.c
  block: Add a new helper to attempt to merge a bio
  block: Remove blk_mq_attempt_merge() function
