Hopefully freedesktop's gitlab efforts will change this someday... also - in the future, if you don't want comments to appear in the patch when they're applied put them below the ---, e.g. the one before the Reviewed-by: tag. Anyway-I'll go ahead and push this, thanks for keeping this list up to date!
