Merge tag 'for-6.9/dm-vdo' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper VDO target from Mike Snitzer:
"Introduce the DM vdo target which provides block-level deduplication,
compression, and thin provisioning. Please see:
Documentation/admin-guide/device-mapper/vdo.rst
Documentation/admin-guide/device-mapper/vdo-design.rst
The DM vdo target handles its concurrency by pinning an IO, and
subsequent stages of handling that IO, to a particular VDO thread.
This aspect of VDO is "unique" but its overall implementation is very
tightly coupled to its mostly lockless threading model. As such, VDO
is not easily changed to use more traditional finer-grained locking
and Linux workqueues. Please see the "Zones and Threading" section of
vdo-design.rst
The DM vdo target has been used in production for many years but has
seen significant changes over the past ~6 years to prepare it for
upstream inclusion. The codebase is still large but it is isolated to
drivers/md/dm-vdo/ and has been made considerably more approachable
and maintainable.
Matt Sakai has been added to the MAINTAINERS file to reflect that he
will send VDO changes upstream through the DM subsystem maintainers"
