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.

([#63176](https://github.com/kubernetes/kubernetes/pull/63176), [@bswartz](https://github.com/bswartz))

 - Scheduler's CycleState now embeds internal read/write locking inside its `Read()` and `Write()` functions. Meanwhile, `Lock()` and `Unlock()` function are removed. Scheduler plugin developers are now required to remove `CycleState#Lock()` and `CycleState#Unlock()`. Just simply use `Read()` and `Write()` as they're natively thread-safe now.

### Bug or Regression

- Allow deletion of pods that use raw block volumes on node reboot ([#122211](https://github.com/kubernetes/kubernetes/pull/122211), [@gnufied](https://github.com/gnufied)) [SIG Node and Storage]

* Fixed binding of block PersistentVolumes / PersistentVolumeClaims when BlockVolume feature is off. ([#84049](https://github.com/kubernetes/kubernetes/pull/84049), [@jsafrane](https://github.com/jsafrane))

- 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 PR ensures it is only called once per volume per node. ([#112403](https://github.com/kubernetes/kubernetes/pull/112403), ...
