Merge tag 'for-5.10/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer:
- Improve DM core's bio splitting to use blk_max_size_offset(). Also
fix bio splitting for bios that were deferred to the worker thread
due to a DM device being suspended.
- Remove DM core's special handling of NVMe devices now that block core
has internalized efficiencies drivers previously needed to be
concerned about (via now removed direct_make_request).
- Fix request-based DM to not bounce through indirect dm_submit_bio;
instead have block core make direct call to blk_mq_submit_bio().
- Various DM core cleanups to simplify and improve code.
- Update DM cryot to not use drivers that set
CRYPTO_ALG_ALLOCATES_MEMORY.
- Fix DM raid's raid1 and raid10 discard limits for the purposes of
linux-stable. But then remove DM raid's discard limits settings now
that MD raid can efficiently handle large discards.
- A couple small cleanups across various targets.
