### Bug or Regression

- Do not expand volume on the node, if controller expansion is finished ([#132010](https://github.com/kubernetes/kubernetes/pull/132010), [@gnufied](https://github.com/gnufied)) [SIG Storage]
- Do not log error event when waiting for expansion on the kubelet ([#132099](https://github.com/kubernetes/kubernetes/pull/132099), [@gnufied](https://github.com/gnufied)) [SIG Storage]

      this.threshold = newTable.length() * 3 / 4; // 0.75
      if (!map.customWeigher() && this.threshold == maxSegmentWeight) {
        // prevent spurious expansion before eviction
        this.threshold++;
      }
      this.table = newTable;
    }

### Bug or Regression

- Do not expand volume on the node, if controller expansion is finished ([#131987](https://github.com/kubernetes/kubernetes/pull/131987), [@gnufied](https://github.com/gnufied)) [SIG Storage]

       * Reclassify nodes in each list to new Map. Because we are using power-of-two expansion, the
       * elements from each bin must either stay at same index, or move with a power of two offset.
       * We eliminate unnecessary node creation by catching cases where old nodes can be reused

### Other (Cleanup or Flake)

- Added the `Step` field to the testing framework to allow volume expansion in configurable step sizes for tests. ([#134760](https://github.com/kubernetes/kubernetes/pull/134760), [@Rishita-Golla](https://github.com/Rishita-Golla)) [SIG Storage and Testing]

* kube-apiserver now includes all registered API groups in discovery, including registered extension API group/versions for unavailable extension API servers. ([#66932](https://github.com/kubernetes/kubernetes/pull/66932), [@nilebox](https://github.com/nilebox))
