- Fixed provisioning of Cinder volumes migrated to CSI when StorageClass with AllowedTopologies was used. ([#98311](https://github.com/kubernetes/kubernetes/pull/98311), [@jsafrane](https://github.com/jsafrane)) [SIG Storage]

* Fixes a NPD bug on GCI, so that it disables glog writing to files for log-counter ([#76211](https://github.com/kubernetes/kubernetes/pull/76211), [@wangzhen127](https://github.com/wangzhen127))
* Fixed parsing of fsType in AWS StorageClass parameters ([#75943](https://github.com/kubernetes/kubernetes/pull/75943), [@jsafrane](https://github.com/jsafrane))

* Reload systemd config files before starting kubelet. ([#65702](https://github.com/kubernetes/kubernetes/pull/65702), [@mborsz](https://github.com/mborsz))
* Fixes an issue where Portworx PVCs remain in pending state when created using a StorageClass with empty parameters ([#64895](https://github.com/kubernetes/kubernetes/pull/64895), [@harsh-px](https://github.com/harsh-px))

- The PersistentVolume controller no longer automatically assigns a default `StorageClass` to Persistent Volume Claims (PVCs) with an empty `storageClassName`.

    Storage class spec:
    kind: StorageClass
    apiVersion: storage.k8s.io/v1
    metadata:
      name: fastpolicy1
    provisioner: kubernetes.io/vsphere-volume
    parameters:
        diskformat: zeroedthick

 - CSI migration of AWS EBS volumes requires AWS EBS CSI driver ver. 1.0 that supports `allowAutoIOPSPerGBIncrease` parameter in StorageClass. ([#101082](https://github.com/kubernetes/kubernetes/pull/101082), [@jsafrane](https://github.com/jsafrane))

### Bug or Regression

- An issues preventing volume expand controller to annotate the PVC with `volume.kubernetes.io/storage-resizer` when the PVC StorageClass is already updated to the out-of-tree provisioner is now fixed.

storage_class  define object level redundancy

ARGS:
standard  (string)    set the parity count for default standard storage class e.g. "EC:4"
rrs       (string)    set the parity count for reduced redundancy storage class e.g. "EC:2"
comment   (sentence)  optionally add a comment to this setting

  much later). ([#122756](https://github.com/kubernetes/kubernetes/pull/122756), [@hakman](https://github.com/hakman)) [SIG Network]
- If a pvc has an empty storageClassName, persistentvolume controller won't try to assign a default StorageClass ([#122704](https://github.com/kubernetes/kubernetes/pull/122704), [@carlory](https://github.com/carlory)) [SIG Apps and Storage]

- The kube-scheduler added support for scheduling hints for the StorageClass resource within the VolumeBinding plugin.
