- Migrated the StatefulSet controller (within `kube-controller-manager`) to use [contextual logging](https://k8s.io/docs/concepts/cluster-administration/system-logs/#contextual-logging) ([#113840](https://github.com/kubernetes/kubernetes/pull/113840),...

### Feature

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

     * The value is, e.g.  <br>
     * @return The value of found property. (NotNull: if not found, exception but basically no way)

     * Get the value for the key 'job.system.property.filter.pattern' as {@link Integer}. <br>

- Migrated `pod-security-admission` to use [contextual logging](https://k8s.io/docs/concepts/cluster-administration/system-logs/#contextual-logging). ([#114471](https://github.com/kubernetes/kubernetes/pull/114471), [@Namanl2001](htt...

* The `system-node-critical` and `system-cluster-critical` priority classes are now limited to the `kube-system` namespace by the `PodPriority` admission plugin. ([#65593](https://github.com/kubernetes/kubernetes/pull/65593), [@bsalamat](https://github.com/bsalamat))

### Other notable changes

- A new kubelet command line option, `--reserved-cpus`, is introduced to explicitly define the CPU list that will be reserved for system. For example, if `--reserved-cpus=0,1,2,3` is specified, then cpu 0,1,2,3 will be reserved for the system.  On a system with 24 CPUs, the user may specify `isolcpus=4-23` for the kernel option and use CPU 4-23 for the user containers.

  - Add support for journald.
  - The ability to monitor any system daemon logs. Previously only kernel
    logs were supported.
  - The ability to be deployed and run as a native daemon.
* **[alpha]** Critical Pods: When feature gate "ExperimentalCriticalPodAnnotation" is
  set to true, the system will guarantee scheduling and admission of pods with

- The `system-node-critical` and `system-cluster-critical` priority classes are now limited to the `kube-system` namespace by the `PodPriority` admission plugin (matching changes in 1.11.1+).

- kubelet now accepts `pid=<number>` in the `--system-reserved` and `--kube-reserved` options to ensure that the specified number of process IDs will be reserved for the system as a whole and for Kubernetes system daemons respectively.  Please reference `Kube Reserved` and `System Reserved` in `Reserve Compute Resources for System Daemons` in the Kubernetes documentation for general discussion of resource reservation.  To utilize this functionality,...
