- For statically provisioned PVs, if their volume source is of CSI type or they have a migrated annotation, when they are deleted, the PersistentVolume controller won't change their phase to the Failed state. With this patch, the external provisioner can remove the finalizer in the next reconcile loop. Unfortunately, if a previously existing PV has the Failed state, this patch won't take effect....

### SIG OpenStack

- Fixed cloud-controller-manager crash when using OpenStack provider and PersistentVolume initializing controller   ([#70459](https://github.com/kubernetes/kubernetes/pull/70459), [@mvladev](https://github.com/mvladev))

### SIG Release

#### Storage

* [stable] Mount options

  * The ability to specify mount options for volumes is moved from beta to stable.

  * A new `MountOptions` field in the `PersistentVolume` spec is available to specify mount options. This field replaces an annotation.

  * A new `MountOptions` field in the `StorageClass` spec allows configuration of mount options for dynamically provisioned volumes.

- Fixed missing `kubelet_volume_stats_*` metrics. ([#133890](https://github.com/kubernetes/kubernetes/pull/133890), [@huww98](https://github.com/huww98)) [SIG Instrumentation and Node]
- Fixed occasional schedule delays when a static `PersistentVolume` is created. ([#133929](https://github.com/kubernetes/kubernetes/pull/133929), [@huww98](https://github.com/huww98)) [SIG Scheduling and Storage]

* fix azure disk attachment error on Linux ([#70002](https://github.com/kubernetes/kubernetes/pull/70002), [@andyzhangx](https://github.com/andyzhangx))
* Fix cloud-controller-manager crash when using OpenStack provider and PersistentVolume initializing controller   ([#70459](https://github.com/kubernetes/kubernetes/pull/70459), [@mvladev](https://github.com/mvladev))

- Fixed a bug that occurred when the hostname label of a node did not match the node name, pods bound to a PersistentVolume with `nodeAffinity` using the hostname may be scheduled to the wrong node or experience scheduling failures.
