Ying's one and mine both has a same effect. Only difference happens swap is full. My version maintains old behavior but Ying's one changes the behavior.

It may be a good thing, since swap will often be freed again (when something is swapped in, or exits). Having some more anonymous pages sit on the inactive list gives them a chance to get used again, potentially giving us a better chance of preserving the working set when swap is full or near full a lot of the time. -- All rights reversed -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
