Hi,
The 1st four patches are optimizations related with bio splitting.
The 5th patch is one fix for using trace_block_plug().
The 6th patch is to mark ctx as pending at batch in flush plug path.
V1:
- 3/6: don't check bio_mergeable() in blk_mq_attempt_merge()
- 4/6: check bio_mergeable() for non-mq too
- 5/6: new patch for fixing using trace_block_plug()
