Why does this need to be a macro (I know we use this for lists and
other places), assuming for now we don't use the iterator pattern, we
can rename mem_cgroup_walk_all() to for_each_mem_cgroup().

Why does this need to be a macro (I know we use this for lists and

can rename mem_cgroup_walk_all() to for_each_mem_cgroup().
