Subject: [PATCH v2 2/5] selftests: memcg: Expect no low events in unprotected sibling
Date:   Wed, 18 May 2022 18:18:56 +0200

This is effectively a revert of commit cdc69458a5f3 ("cgroup: account
for memory_recursiveprot in test_memcg_low()"). The case test_memcg_low
will fail with memory_recursiveprot until resolved in reclaim
code.
However, this patch preserves the existing helpers and variables for
later uses.
