If the bug is serious enough to justify a -stable backport then yes, we should merge a fix such as this ahead of the fscache rewrite, so we have something suitable for backporting. Is the bug serious enough? Or is the bug in a not-yet-noticed state? In other words, is it possible that four years from now, someone will hit this bug in a 5.15-based kernel and will then wish we'd backported a fix?
