- local: support local filesystem volume with block resource reconstruction ([#84218](https://github.com/kubernetes/kubernetes/pull/84218), [@cofyc](https://github.com/cofyc))

- Reverted NewVolumeManagerReconstruction and SELinuxMountReadWriteOncePod feature gates to disabled by default to resolve a regression of volume reconstruction on kubelet/node restart ([#117752](https://github.com/kubernetes/kubernetes/pull/117752), [@liggitt](https://github.com/liggitt)) [SIG Storage]

* Delay CSI client initialization to make reconstruction of CSI volume possible because clients may not be available on kubelet restart. ([#74652](https://github.com/kubernetes/kubernetes/pull/74652), [@cofyc](https://github.com/cofyc))

- Fixed Pod stuck in `Terminating` because of `GenerateUnmapVolumeFunc` missing `globalUnmapPath` when kubelet tries to clean up all volumes that failed reconstruction. ([#123032](https://github.com/kubernetes/kubernetes/pull/123032), [@carlory](https://github.com/carlory))

With a few exceptions, Istio controllers typically are split in two phases: construction and running.

Construction should create informers (via `kclient.New`), setup a queue (via `controllers.NewQueue`), and register event handlers on the informers.
Often, these handlers are adding something to the queue like `client.AddEventHandler(controllers.ObjectHandler(queue.AddObject))`.
