Subject: [git pull] device mapper changes for 5.10
Date: Tue, 13 Oct 2020 11:40:00 -0400 [thread overview]
Message-ID: <20201013154000.GA53766@lobo> (raw)
Hi Linus,
This pull's changes depend on various linux-block changes (as noted in
the refernced merge commit's header).
The following changes since commit 1471308fb5ec4335f9ae9fc65f65048dbe7c336e:
Merge remote-tracking branch 'jens/for-5.10/block' into dm-5.10 (2020-09-29 16:31:35 -0400)

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.
