SubjectRe: RFC: reviewer's statement of oversight
On Monday October 8, wrote:

I find it is always good to know *why* we have the tags. That
information is a useful complement to what they mean, and can guide
people in adding them.

So below I present some "Purposes", YetAnotherTag, and a comment on
the RSO.

(And I'd like to add a vote for "Blame-Shared-By:" rather than
"Reviewed-by:", however I don't I'll get much support...)

From: The Author, Primary Author, or Authors of the patch.
Authors should also provide a Signed-off-by: tag.

Purpose: to inform upstream aggregators that
consensus was achieved for the change. This is
particularly relevant for changes that affect multiple

This seems more detailed that necessary. The process (communicated
back / responded) is not really relevant. I would go for something

(b) I have no outstanding problems, concerns, or questions about
this patch (except as noted in the above comments).

and in fact, given (c2), (b) might not be needed at all.
