- If using cgroups v2, then the cgroup aware OOM killer will be enabled for container cgroups via  `memory.oom.group` .  This causes processes within the cgroup to be treated as a unit and killed simultaneously in the event of an OOM kill on any process in the cgroup.

### Feature

- A `system-cluster-critical` pod should not get a low OOM Score.

- Bump node-problem-detector version to v0.8.5 to fix OOM detection in with Linux kernels 5.1+ ([#96716](https://github.com/kubernetes/kubernetes/pull/96716), [@tosi3k](https://github.com/tosi3k)) [SIG Cloud Provider, Scalability and Testing]

### Documentation

- Documented the reason field in CRI API to ensure it equals `OOMKilled` for the containers terminated by OOM killer ([#112977](https://github.com/kubernetes/kubernetes/pull/112977), [@mimowo](https://github.com/mimowo))
