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 block/blk-core.c | 156 -------------------------------------- block/blk-merge.c | 202 +++++++++++++++++++++++++++++++++++++++++++++++++ block/blk-mq-sched.c | 94 +++++------------------ block/blk.h | 23 ++++-- block/kyber-iosched.c | 2 +- include/linux/blk-mq.h | 2 - 6 files changed, 239 insertions(+), 240 deletions(-) -- 1.8.3.1
