Subject: memcg: use ifdef for mem_cgroup_is_obsolete()
From: Pekka Enberg <penberg@xxxxxxxxxxxxxx>
When CONFIG_DEBUG_VM is disabled, I get the following warning:
CC mm/memcontrol.o
mm/memcontrol.c:318: warning: `mem_cgroup_is_obsolete' defined but not
used
Fix that up by wrapping mem_cgroup_is_obsolete() in an ifdef.
