Merge tag 'for-5.18/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer: - Significant refactoring and fixing of how DM core does bio-based IO accounting with focus on fixing wildly inaccurate IO stats for dm-crypt (and other DM targets that defer bio submission in their own workqueues). End result is proper IO accounting, made possible by targets being updated to use the new dm_submit_bio_remap() interface. - Add hipri bio polling support (REQ_POLLED) to bio-based DM. - Reduce dm_io and dm_target_io structs so that a single dm_io (which contains dm_target_io and first clone bio) weighs in at 256 bytes. For reference the bio struct is 128 bytes. - Various other small cleanups, fixes or improvements in DM core and targets. - Update MAINTAINERS with my kernel.org email address to allow distinction between my "upstream" and "Red" Hats. * tag 'for-5.18/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (46 commits) dm: consolidate spinlocks in dm_io struct dm: reduce size of dm_io and dm_target_io structs dm: switch dm_target_io booleans over to proper flags dm: switch dm_io booleans over to proper flags dm: update email address in MAINTAINERS dm: return void from __send_empty_flush dm: factor out dm_io_complete dm cache: use dm_submit_bio_remap dm: simplify dm_sumbit_bio_remap interface dm thin: use dm_submit_bio_remap dm: add WARN_ON_ONCE to dm_submit_bio_remap dm: support bio polling block: add ->poll_bio to block_device_operations dm mpath: use DMINFO instead of printk with KERN_INFO dm: stop using bdevname dm-zoned: remove the ->name field in struct dmz_dev dm: remove unnecessary local variables in __bind dm: requeue IO if mapping table not yet available dm io: remove stale comment block for dm_io() dm thin metadata: remove unused dm_thin_remove_block and __remove ...
