This commit message doesn't state why. The cover letter does, but that
doesn't get checked into git. A year from now, if someone lands on this
commit during a bisect, it would help if the commit message told them
why you are adding a no-op callback here, instead of trying to fix the
caller to treat a NULL callback as acceptable.
