v7: - Skip the vmscan change as the mem_cgroup_usage() check for now as it is currently redundant.
v6: - The memcg_test_low failure is indeed due to the memory_recursiveprot mount option which is enabled by default in systemd cgroup v2 setting. So adopt Michal's suggestion to adjust the low event checking according to whether memory_recursiveprot is enabled or not.
v5: - Use mem_cgroup_usage() in patch 1 as originally suggested by Johannes.
The test_memcontrol selftest consistently fails its test_memcg_low sub-test (with memory_recursiveprot enabled) and sporadically fails its test_memcg_min sub-test. This patchset fixes the test_memcg_min and test_memcg_low failures by adjusting the test_memcontrol selftest to fix these test failures.
Waiman Long (2): selftests: memcg: Allow low event with no memory.low and memory_recursiveprot on selftests: memcg: Increase error tolerance of child memory.current check in test_memcg_protection()
