Subject: [PATCH 6.6 v2 0/6] md/md-bitmap: move bitmap_{start, end}write to md upper layer

From: Yu Kuai <yukuai3@...wei.com>

Changes in v2:
 - Add descriptions about chagnes from the original commits, in order to
 fix conflicts.

This set is actually a refactor, we're bacporting this set because
following problems can be fixed:

https://lore.kernel.org/all/ADF7D720-5764-4AF3-B68E-1845988737AA@flyingcircus.io/

See details in patch 6.

I'll suggest people to upgrade their kernel to v6.6+, please let me know
if anyone really want this set for lower version.

Benjamin Marzinski (1):
  md/raid5: recheck if reshape has finished with device_lock held

Yu Kuai (5):
  md/md-bitmap: factor behind write counters out from
    bitmap_{start/end}write()
  md/md-bitmap: remove the last parameter for bimtap_ops->endwrite()
  md: add a new callback pers->bitmap_sector()
  md/raid5: implement pers->bitmap_sector()
  md/md-bitmap: move bitmap_{start, end}write to md upper layer
