    memory cgroup enhancements: fix zone handling in try_to_free_mem_cgroup_page · 417eead3

    Because NODE_DATA(node)->node_zonelists[] is guaranteed to contain all
    necessary zones, it is not necessary to use for_each_online_node.
    
    And this for_each_online_node() makes reclaim routine start always
    from node 0. This is not good. This patch makes reclaim start from
    caller's node and just use usual (default) zonelist order.
