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? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/ .
