That sounds good.

Or it can be more efficient for productions:
Linux can merge your patches and ACPICA just stop to take them.
This will leave us divergences.
After the table manager cleanups are tested and shipped in the ACPICA repo, the new facilities will automatically be rolled into Linux branches.
Then I can help to reduce the divergences using the new ACPICA facilities.
At that time I may ask whoever that can test to offer help to review the cleanup patch.

Thanks and best regards
