Can you, confirm that whether this test is still failed when
memory.use_hierarchy is 0?


Test A:
1, reboot your system
2, ehco 0 >/sys/fs/cgroup/memory/memory.use_hierarchy
3, Run the ltp testcase: memcg_usage_in_bytes_test.sh


Test B:
1, reboot
2, ehco 1 >/sys/fs/cgroup/memory/memory.use_hierarchy
3, Run the ltp testcase: memcg_usage_in_bytes_test.sh


Which one(Test A or B?) you can get PASS on your ARM board?
