- For raw block CSI volumes on Kubernetes, kubelet was incorrectly calling CSI `NodeStageVolume` for every single "map" (i.e. raw block "mount") operation for a volume already attached to the node. This change modified that behavior to ensure it is only called once per volume per node. ([#112403](https://github.com/k...

#### Storage
- A node that uses a CSI raw block volume needs to be drained before kubelet can be upgraded to 1.17. ([#74026](https://github.com/kubernetes/kubernetes/pull/74026), [@mkimuram](https://github.com/mkimuram))

#### Windows

SIG Storage made a lot of progress in the 1.18 release.
In particular, the following storage features are moving to GA in Kubernetes 1.18:
- Raw Block Support: Allow volumes to be surfaced as block devices inside containers instead of just mounted filesystems.
- Volume Cloning: Duplicate a PersistentVolumeClaim and underlying storage volume using the Kubernetes API via CSI.
