Warning: procedural nitpicking ahead ...
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 :)
