This is not what people normally do when given suggestion diff like
what I sent before [1]. Instead, they just apply and squash the
suggestion (while also applying requested changes from reviewers).

Please reroll your series [2] with suggestion applied.

Thanks.

No, this is the correct course of action. There isn't any point in
having an *unrelated* change in a separate series. This is a
standalone change, posted as a standalone patch.

Or not.

You mean the series before this patch have already been applied,
right?

This change is 100% independent from the series you quoted. Why should
there be a dependency between the two?

As for respinning the series at this stage for a documentation
formatting issue, this is pretty pointless, and only clutters people's
Inbox with redundant versions...
