kernel:
# uname -r

[期望结果]：
用例PASS

[实际结果]：
用例FAIL

[初步分析]：
       echo 1 > memory.use_hierarchy

        mkdir subgroup
        echo 4096 > memory.limit_in_bytes
        echo 8192 > subgroup/memory.limit_in_bytes

        cd subgroup
       执行以上命令后，通过memory.stat中读取到的hierarchical_memory_limit的值，预期是4096，读取的值为8192
        check_mem_stat "hierarchical_memory_limit" 4096
