I think this patch stands on its own merits. It fixes two bugs: one is an annoyance for those of us who use stress-ng and the other bug is purely theoretical (thus far). This fix can be merged independently of related bugs, even if those bugs have similar fixes, because separate patches are usually preferable, because a 'git revert' is usually a possibility.
