For a function <code>f</code>, the iteration proceeds by calling <code>f</code>
with a new, synthesized <code>yield</code> function as its argument.
If <code>yield</code> is called before <code>f</code> returns,
the arguments to <code>yield</code> become the iteration values
for executing the loop body once.
After each successive loop iteration, <code>yield</code> returns true
and may be called again to continue the loop.

- Fix: Mount point may become local without calling NodePublishVolume after node rebooting. ([#119923](https://github.com/kubernetes/kubernetes/pull/119923), [@cvvz](https://github.com/cvvz)) [SIG Node and Storage]

- 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.

* [stable] Expose storage usage metrics

  * The available capacity of a given Persistent Volume (PV) is available by calling the Kubernetes metrics API.

* [stable] Volume plugin metrics

  * Success and latency metrics for all Kubernetes calls are available by calling the Kubernetes metrics API. You can request volume operations, including mount, unmount, attach, detach, provision, and delete.

* Implement dependency cache per request.
    * This avoids calling each dependency multiple times for the same request.
    * This is useful while calling external services, performing costly computation, etc.
