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.
