From fd538803731e50367b7c59ce4ad3454426a3d671 Mon Sep 17 00:00:00 2001 From: Michal Hocko Date: Wed, 22 Feb 2017 15:45:58 -0800 Subject: mm, vmscan: cleanup lru size claculations lruvec_lru_size returns the full size of the LRU list while we sometimes need a value reduced only to eligible zones (e.g. for lowmem requests). inactive_list_is_low is one such user. Later patches will add more of them. Add a new parameter to lruvec_lru_size and allow it filter out zones which are not eligible for the given context.
