v8:
- Ignore the low event count of child 2 with memory_recursiveprot on
in patch 1 as originally suggested by Michal.
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.
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()
