ster/cpu-management-policies/), which allows users to request exclusive CPU cores.  This helps performance in a variety of use-cases, including network latency sensitive applications, as well as applications that benefit from CPU cache residency.  Next, [Huge Pages](https://kubernetes.io/docs/tasks/manage-hugepages/scheduling-hugepages/), which allows pods to consume either 2Mi or 1Gi Huge Pages.  This benefits applications that consume large amounts of memory.  Use of Huge Pages is a common tuning...

- `--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...

- To enhance usability and developer experience, CRD validation rules now support direct use of (CEL) reserved keywords as field names in object validation expressions for existing expressions in storage, will fully support runtime in next release for compatibility concern.

PVs, if its volume source is CSI type or it has migrated annotation, when it's deleted, the PersisentVolume controller won't changes its phase to the Failed state. 
  
  With this patch, the external provisioner can remove the finalizer in next reconcile loop. Unfortunately if the provious existing pv has the Failed state, this patch won't take effort. It requires users to remove finalizer. ([#126045](https://github.com/kubernetes/kubernetes/pull/126045), [@carlory](https://github.com/carlory))...

SIG Storage also worked on a number of [Container Storage Interface (CSI) features](https://github.com/kubernetes/enhancements/issues/178) this quarter in anticipation of moving support for CSI from beta to GA in the next Kubernetes release. This includes graduating the dependent “mount namespace propagation” feature to GA, moving the Kubelet plugin registration mechanism to beta, adding alpha support for a new CSI driver registry as well as for topology, and adding...

- The metadata.clusterName field is deprecated. This field has always been unwritable and always blank, but its presence is confusing, so we will remove it next release. Out of an abundance of caution, this release we have merely changed the name in the go struct to ensure any accidental client uses are found before complete removal.
