- 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.

- Add e2e test to node expand volume with secret ([#115451](https://github.com/kubernetes/kubernetes/pull/115451), [@zhucan](https://github.com/zhucan)) [SIG Storage and Testing]

- 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.

Channels act as first-in-first-out queues.
For example, if one goroutine sends values on a channel
and a second goroutine receives them, the values are
received in the order sent.
