The usual tag for someone that found a bug in an earlier version of a patch would be Reviewed-by:. Is there any reason we can't use that here? The "syzbot+..." email should be enough on its own, I can't see a reason why their scripts would need to require a particular tag. Or maybe we could use Tested-by:, or some other tag made up for this case? I do worry that someone who sees "Reported-by:..." might for example mistakenly assume that it would help to backport that patch if they see a similar-looking oops. --b.
