yeah - it just makes it a tiny bit harder decision whether to queue up a
patch in the urgent path.
It's better to keep cleanups separate - that way any typos and
unintended bugs in cleanups are more obvious as well. (because later on
a person debugging a breakage does not have to wonder about whether a
change's side-effects were intended or not.)
But your patch certainly looks OK standalone as well, just IMO not as a
very-last-minute patch. (No strong feelings though, your patch should
not break anything in the normal !CPUSETS or the CPUSETS+no-cpuset-used
usecases.)
