The patch titled
     memory controller enhancements for reclaiming take2: define free_mem_cgroup_per_zone_info
has been added to the -mm tree.  Its filename is

Subject: memory controller enhancements for reclaiming take2: define free_mem_cgroup_per_zone_info
From: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com>

Now allocation of per_zone of mem_controller is done by
alloc_mem_cgroup_per_zone_info(). Then it will be good to use
free_mem_cgroup_per_zone_info() for maintainance.
