From a6cccdc36c966e51fd969560d870cfd37afbfa9c Mon Sep 17 00:00:00 2001 From: KOSAKI Motohiro Date: Tue, 24 May 2011 17:11:33 -0700 Subject: mm, mem-hotplug: update pcp->stat_threshold when memory hotplug occur Currently, cpu hotplug updates pcp->stat_threshold, but memory hotplug doesn't. There is no reason for this.
