Hi Andrew,

After merging the akpm-current tree, today's linux-next build
(x86_64 allmodconfig) failed like this:

mm/memcontrol.c: In function '__mem_cgroup_iter_next':
mm/memcontrol.c:982:4: error: 'prev_cgroup' undeclared (first use in this function)
    prev_cgroup = next_cgroup;
    ^
mm/memcontrol.c:982:18: error: 'next_cgroup' undeclared (first use in this function)
    prev_cgroup = next_cgroup;
                  ^

I applied this patch:
