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
in portable persistent data.
