- Add `csi_operations_seconds` metric on kubelet that exposes CSI operations duration and status for node CSI operations. ([#98979](https://github.com/kubernetes/kubernetes/pull/98979), [@Jiawei0227](https://github.com/Jiawei0227)) [SIG Instrumentation 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 PR ensures it is only called once per volume per node.
