From 1a687c2e9a99335c9e77392f050fe607fa18a652 Mon Sep 17 00:00:00 2001 From: Mel Gorman Date: Thu, 22 Nov 2012 11:16:36 +0000 Subject: mm: sched: numa: Control enabling and disabling of NUMA balancing This patch adds Kconfig options and kernel parameters to allow the enabling and disabling of automatic NUMA balancing. The existance of such a switch was and is very important when debugging problems related to transparent hugepages and we should have the same for automatic NUMA placement.
