* The strategicmerge patchMergeKey for VolumeMounts was changed from "name" to "mountPath".  This was necessary because the name field refers to the name of the Volume, and is not a unique key for the VolumeMount.  Multiple VolumeMounts will have the same Volume name if mounting the same volume more than once.  The "mountPath" is verified to be unique and can act as the mergekey.

SIG Storage continued work to [enable migration of in-tree volume plugins](https://github.com/kubernetes/enhancements/issues/625) to the Container Storage Interface (CSI). SIG Storage worked on bringing CSI to feature parity with in-tree functionality, including functionality like resizing, inline volumes, and more. SIG Storage introduces new alpha functionality in CSI that doesn't exist in the Kubernetes Storage subsystem yet, like volume cloning.

Volume cloning enables users to specify...

- Fixed attaching volumes after detach errors. Now volumes that failed to detach are not treated as attached, Kubernetes will make sure they are fully attached before they can be used by pods.

  It matches all PVC objects that have the volume attributes class mentioned. 
  

- Adds PV deletion protection finalizer only when PV reclaimPolicy is Delete for dynamically provisioned volumes. ([#109205](https://github.com/kubernetes/kubernetes/pull/109205), [@deepakkinni](https://github.com/deepakkinni))
- Allowed attached volumes to be mounted quicker by skipping exponential backoff when checking for reported-in-use volumes. ([#106853](https://github.com/kubernetes/kubernetes/pull/106853), [@gnufied](https://github.com/gnufied))

- Kubelet: Fix the volume manager didn't check the device mount state in the actual state of the world before marking the volume as detached. It may cause a pod to be stuck in the Terminating state due to the above issue when it was deleted. ([#129063](https://github.com/kubernetes/kubernetes/pull/129063), [@carlory](https...
