From 0b1303fcf23678ee1785841fb0c770a35cd0833c Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Fri, 24 Mar 2006 03:15:59 -0800 Subject: [PATCH] [PATCH] cpusets: only wakeup kswapd for zones in the current cpuset If we get under some memory pressure in a cpuset (we only scan zones that are in the cpuset for memory) then kswapd is woken up for all zones. This patch only wakes up kswapd in zones that are part of the current cpuset.
