Thank you!
Hi Linus, The following changes since commit 54be6c6c5ae8e0d93a6c4641cb7528eb0b6ba478: Linux 6.8-rc3 (2024-02-04 12:20:36 +0000) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git tags/for-6.9/dm-vdo for you to fetch changes up to cb824724dccb3195d22cad96e7b65fe13621d0a6: dm vdo: document minimum metadata size requirements (2024-03-07 19:56:24 -0500) Please pull, thanks. Mike ---------------------------------------------------------------- - Introduce the DM vdo target which provides block-level deduplication, compression, and thin provisioning. Please see both: Documentation/admin-guide/device-mapper/vdo.rst and 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. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAmXqYlEACgkQxSPxCi2d
