Only in a single case: where a zone is all_unreclaimable and some pages
have recently become reclaimable but we don't know about it yet.
Certainly it can happen, but it sounds really unlikely to me. So I suspect
that if you were to fix that problem by some means, it wouldn't help
anything.
But maybe I'm wrong, or maybe the all_unreclaimable logic has rotted. Have
you tried simply disabling it?
