[PATCH v3 0/6] dm: fix then improve bio splitting

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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()
