I don't see anything above that says I can't add this tag if I reported
(by sending an email about the problem to the list), debugged, and
solved the problem by sending a patch.

I don't see how this is the same. It certainly is not explicit, as you
say.

I wouldn't have added the tag if I didn't send an email to the list with
the lockdep splat and follow that up with a bisection report for
suspend/resume being broken. Shouldn't we value those sorts of bug
report emails? I will add a link to the report in the commit text to
clarify.

Ok, so is it just a shock to see this for the first time? What is the
problem with the tag? Can you elaborate on your concerns? I would like
to understand.
