- `--log-flush-frequency` had no effect in several commands or was missing. Help and warning texts were not always using the right format for a command (`add_dir_header` instead of `add-dir-header`). Fixing this included cleaning up flag handling in component-base/logs: that package no longer adds flags to the global flag sets. Commands which want the klog and `--log-flush-frequency`...

- The `kube-proxy` log now shows the "Skipping topology aware endpoint filtering since no hints were provided for zone" warning under the right conditions. ([#101857](https://github.com/kubernetes/kubernetes/pull/101857), [@dervoeti](https://github.com/dervoeti))

- Overall, enable the feature of `PreferNominatedNode` will  improve the performance of scheduling where preemption might frequently happen, but in theory, enable the feature of `PreferNominatedNode`, the pod might not be scheduled to the best candidate node in the cluster.

 - CSINode initialization does not crash kubelet on startup when APIServer is not reachable or kubelet has not the right credentials yet. ([#89589](https://github.com/kubernetes/kubernetes/pull/89589), [@jsafrane](https://github.com/jsafrane)) [SIG Storage]

  which the scheduler might miss some updates for the Pods rejected by NodeUnschedulable plugin and put the Pods in the queue for a longer time than needed. ([#127427](https://github.com/kubernetes/kubernetes/pull/127427), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]
