Maybe the Active page bit could be overloaded with some minor rewriting? IOW, perhaps the Active bit could be ignored when the page is moved to the inactive LRU? (Confusing I know, but I am just brainstorming...)
The PG_referenced bit is already overloaded. We keep the bit set when we move a page from the active to the inactive list, so a page that was previously active only needs to be referenced once to become active again. The LRU bits (PG_lru, PG_active, etc) are needed to figure out which LRU list the page is on. I don't think we can overload those... -- All rights reversed -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
