So it doesn't look like a stable > material. The stable backportability would be limited as there's a prerequisity on the "mm: page_alloc: freelist migratetype hygiene" patchset from half a year ago - patch applicability wise and importantly functionality wise. Otherwise the counter could drift easily. However we could perhaps mark it for a 6.12 stable backport as that's presumably the upcoming LTS.
