Jones <luke@ljones.dev> Luke, As I've seen you use S-o-b tag a few times like this, do you actually mean Reviewed-by: tag which tells you've looked through the change and think it's good/useful for the kernel? S-o-b relates to authorship of the code in the patch (and should be there right from the submission, not added like this).
