Hi, This patchset reflects a baseline of the VDO DM target. It is still very much under active review and development, and will likley continue to be until the end of this year. So while the code isn't yet ready for upstream inclusion it will evolve so that one day it hopefully is, and moving forward that evolution will be visible both on dm-devel and in this linux-dm.git 'dm-vdo' branch: https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=dm-vdo
I've already made a series of changes to this baseline which are visible on this 'dm-vdo-wip' branch: https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=dm-vdo-wip As you'll see: a lot of coding style, whitespace, and data structure and file renames -- and there is much more to come. dm-vdo-wip will always be based on dm-vdo, but both branches will be periodically rebased to track the main linux-dm.git upstream DM changes over time (e.g. they are currently based on 'dm-6.5' but will be rebased as needed). I've been working with Matt Sakai to help him understand the upstream Linux release cadance and associated git workflows. Matt isn't yet named in MAINTAINERS in the 'dm-vdo' branch but will be in the near future. Matt will be the upstream maintainer for the dm-vdo target. Thanks, Mike Matthew Sakai (39): dm: add documentation for dm-vdo target dm vdo: add the MurmurHash3 fast hashing algorithm dm vdo: add memory allocation utilities dm vdo: add basic logging and
