  - PreemptionByKubeScheduler (Pod preempted by kube-scheduler)
  - DeletionByTaintManager (Pod deleted by taint manager due to NoExecute taint)
  - EvictionByEvictionAPI (Pod evicted by Eviction API)
  - DeletionByPodGC (an orphaned Pod deleted by PodGC) ([#110959](https://github.com/kubernetes/kubernetes/pull/110959), [@mimowo](https://github.com/mimowo))
- Kube-Scheduler ComponentConfig is graduated to GA, `kubescheduler.config.k8s.io/v1` is available now.

- Fix: After a Node is down and take some time to get back to up again, the mount point of the evicted Pods cannot be cleaned up successfully. (#111933) Meanwhile Kubelet will print the log `Orphaned pod "xxx" found, but error not a directory occurred when trying to remove the volumes dir` every 2 seconds.
