The 'Signed-off-by' tag is in reference to the DCO, which makes sense to add if you are a patch author or are merging a patch into a tree, but it doesn't make much sense as a ACK/thumbs-up; this is why we have the 'Acked-by' and 'Reviewed-by' tags. I generally read the 'Acked-by' tag as "I'm the one responsible for a chunk of code affected by this patch and I'm okay with this change" and the 'Reviewed-by' tag as "I looked at this patch and it looks like a good change to me". Perhaps surprisingly to some, while an 'Acked-by' is a requirement for merging in a lot of cases, I appreciate 'Reviewed-by' tags much more as it indicates the patch is getting some third-part eyeballs on it ... so all you lurkers on this list, if you're reviewing patches as they hit your inbox, don't be shy about posting your 'Reviewed-by' tag if your comfortable doing so, we all welcome the help :) https://www.kernel.org/doc/html/latest/process/submitting-patches.html#sign-your-work-the-developer-s-certificate-of-origin -- paul-moore.com
