Re: [PATCH kselftest-next 1/2] kselftests: memcg: update the oom group leaf events test

Roman Gushchin writes:

Commit 9852ae3fe529 ("mm, memcg: consider subtrees in memory.events") made memory.events recursive: all events are propagated upwards by the tree. It was a change in semantics.

It broke the oom group leaf events test: it assumes that after an OOM the oom_kill counter is zero on parent's level.

Let's adjust the test: it should have similar expectations for the child and parent levels.

The test passes after this fix.

Thanks! Hopefully b59b1baa will also avoid this going unnoticed in future.
