There was a problem hiding this comment.
Move this closer to where t-2 is used?

It was confusing to me to see the %s argument repeated. Maybe a comment to explain the intent might help?

`InstrProfWriter::addTemporalProfileTraces()` did not correctly account for when the sources traces are sampled, but the reservoir size is larger than what it was before, meaning there is room for more traces. Also, if the reservoir size decreased, meaning traces should be truncated. Depends on #152550 for the test refactor
