So that's an Ack. Leaving a Rb tag for a tiny tiny piece of big patch
will give impression that everything is reviewed on v13. And the patch
was not reviewed by you.

If you cannot certify the reviewers statement of oversight then use acked

"For instance, maintainers may use it to signify that they are OK with a
patch landing, but they may not have reviewed it as thoroughly as if a
Reviewed-by: was provided."

"For example, if a patch affects multiple subsystems and has an
Acked-by: from one subsystem maintainer then this usually indicates
acknowledgement of *just the part which affects that maintainer's code.*"


Best regards,
