From 2e9c23724328ae4e56c42a35a717a956d7d3001d Mon Sep 17 00:00:00 2001 From: KAMEZAWA Hiroyuki Date: Wed, 11 Feb 2009 13:04:29 -0800 Subject: [PATCH] memcg: use __GFP_NOWARN in page cgroup allocation page_cgroup's page allocation at init/memory hotplug uses kmalloc() and vmalloc(). If kmalloc() failes, vmalloc() is used. This is because vmalloc() is very limited resource on 32bit systems. We want to use kmalloc() first. But in this kind of call, __GFP_NOWARN should be specified.
