* Prevent hotloops on error conditions, which could fill up the disk faster than log rotation can free space. ([#40497](https://github.com/kubernetes/kubernetes/pull/40497), [@lavalamp](https://github.com/lavalamp))

### Cloud Provider

#### AWS

* Volume metrics support for vSphere Cloud Provider has been added. You can now monitor available space, capacity, and used space on volumes created using vSphere. ([#59328](https://github.com/kubernetes/kubernetes/pull/59328), [@divyenpatel](https://github.com/divyenpatel))

* Bug fixes

  * Changed Kubelet default image-gc-high-threshold to 85% to resolve a conflict with default settings in docker that prevented image garbage collection from resolving low disk space situations when using devicemapper storage. ([#40432](https://github.com/kubernetes/kubernetes/pull/40432), [@sjenning](https://github.com/sjenning))

- Kubeadm: fixed missing space when printing the warning about pause image mismatch. ([#131563](https://github.com/kubernetes/kubernetes/pull/131563), [@logica0419](https://github.com/logica0419)) [SIG Cluster Lifecycle]

- `kubeadm`: updated warning message when swap space is detected. When swap is
  active on Linux, `kubeadm` explains that swap is supported for cgroup v2 only and

- Added a "reason" field to the "image_garbage_collected_total" metric, allowing administrators to differentiate between images that were collected for reasons "age" vs "space".
   ([#123345](https://github.com/kubernetes/kubernetes/pull/123345), [@haircommander](https://github.com/haircommander))

- Kubeadm: make sure the etcd static pod startup probe uses /health?serializable=false while the liveness probe uses /health?serializable=true&exclude=NOSPACE. The NOSPACE exclusion would allow administrators to address space issues one member at a time. ([#110744](https://github.com/kubernetes/kubernetes/pull/110744), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

  * You can now set container requests, container limits, and node allocatable reservations for the new `ephemeral-storage` resource.

  * The `ephemeral-storage` resource includes all the disk space a container might consume with container overlay or scratch.

* [alpha] Mount namespace propagation

  * The `VolumeMount.Propagation` field for `VolumeMount` in pod containers is now available.

### Kubernetes Node system swap support

Every system administrator or Kubernetes user has been in the same boat regarding setting up and using Kubernetes: disable swap space. With the release of Kubernetes 1.22, *alpha* support is available to run nodes with swap memory. This change lets administrators opt in to configuring swap on Linux nodes, treating a portion of block storage as additional virtual memory.
