 - `BlockVolume`: Enable the definition and consumption of raw block devices in Pods.

+- `BoundServiceAccountTokenVolume`: Migrate ServiceAccount volumes to use a projected volume consisting of a

 - `CPUManager`: Enable container level CPU affinity support, see [CPU Management Policies](/docs/tasks/administer-cluster/cpu-management-policies/).
 - `CRIContainerLogRotation`: Enable container log rotation for cri container runtime.
 - `CSIBlockVolume`: Enable external CSI volume drivers to support block storage. See the [`csi` raw block volume support](/docs/concepts/storage/volumes/#csi-raw-block-volume-support) documentation for more details.

 - `KubeletPluginsWatcher`: Enable probe-based plugin watcher utility to enable kubelet
   to discover plugins such as [CSI volume drivers](/docs/concepts/storage/volumes/#csi).
+- `KubeletPodResources`: Enable the kubelet's pod resources grpc endpoint.

 - `LocalStorageCapacityIsolation`: Enable the consumption of [local ephemeral storage](/docs/concepts/configuration/manage-compute-resources-container/) and also the `sizeLimit` property of an [emptyDir volume](/docs/concepts/storage/volumes/#emptydir).
 - `MountContainers`: Enable using utility containers on host as the volume mounter.
 - `MountPropagation`: Enable sharing volume mounted by one container to other containers or pods.
