Hi Jens,
  It is still unclear whether the support for non-po2 zone size devices
  will be added anytime soon [1]. I have extracted out the cleanup
  patches that doesn't do any functional change but improves the
  readability by adding helpers. This also helps a bit to
  maintain off-tree support as there is an interest to have this feature
  in some companies.

I have retained the reviewed by tags for the commits that did not change
from the main patches I sent before[1].

Luis Chamberlain (1):
  dm-zoned: ensure only power of 2 zone sizes are allowed

Pankaj Raghav (6):
  block: remove superfluous check for request queue in bdev_is_zoned
  block: add a new helper bdev_{is_zone_start, offset_from_zone_start}
  nvmet: introduce bdev_zone_no helper
  zonefs: use bdev_zone_no helper to calculate the zone index
  dm-zone: use generic helpers to calculate offset from zone start
  dm: call dm_zone_endio after the target endio callback for zoned
    devices
