DESCRIPTION
The inactive anon list should be small enough that the VM never has to do too much work, but large enough that each inactive page has a chance to be referenced again before it is swapped out.
The inactive_anon ratio is the target ratio of ACTIVE_ANON to INACTIVE_ANON pages on this zone's LRU, maintained by the pageout code. A zone->inactive_ratio of 3 means 3:1 or 25% of the anonymous pages are kept on the inactive list.
