selftests: cgroup: add zswap-memcg unwanted writeback test
Add a test to verify that when a memcg hits its limit in zswap, it doesn't
trigger an unwanted writeback that would result in pages not owned by that
memcg to be sent to disk, even if zswap isn't full. This was fixed by
commit 0bdf0efa180a("zswap: do not shrink if cgroup may not zswap").
