Once vmscan sees the page and tries to liberate it, then it will be unlarge'd and thus you'll get fine-grained page aging. That's the beauty of my implementation suggestion. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
