dm: fix request-based DM to not bounce through indirect dm_submit_bio (2020-10-07 18:08:51 -0400)
Please pull, thanks.
Mike
----------------------------------------------------------------
- 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.
