#     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"
