Hi,
Patches 1 and 2 are queued for me to send to Linus later this week.
Patches 3 and 4 are block core and should get picked up for 5.10.
Jens, please pick them up. I revised the header for patch 4 to give
better context for use-case where non power-of-2 chunk_sectors
occurs. Patch 4 enables DM to switch to using blk_max_size_offset() in
Patch 6.
Patches 5 and 6 just show how DM will be enhanced for 5.10 once
patches 3 and 4 land in the block tree.
Mike Snitzer (6):
dm: fix bio splitting and its bio completion order for regular IO
dm: fix comment in dm_process_bio()
block: use lcm_not_zero() when stacking chunk_sectors
block: allow 'chunk_sectors' to be non-power-of-2
dm table: stack 'chunk_sectors' limit to account for target-specific splitting
dm: change max_io_len() to use blk_max_size_offset()
