* Fixes a bug where kubelet crashes trying to free memory under memory pressure. ([#58574](https://github.com/kubernetes/kubernetes/pull/58574), [@yastij](https://github.com/yastij))

  // Must be an empty string (default) or Memory.
  // More info: https://kubernetes.io/docs/concepts/storage/volumes#emptydir
  // +optional
  optional string medium = 1;

  // sizeLimit is the total amount of local storage required for this EmptyDir volume.
  // The size limit is also applicable for memory medium.
  // The maximum usage on memory medium EmptyDir would be the minimum value between

  Burstable QoS pods. For Best-Effort/Guaranteed QoS pods, swap would be disabled.
  
  Containers with memory requests equal to their memory limits also won't have
  swap access, and it is a way to opt-out of swap for a single container.
  
  The formula for the swap limit for Burstable QoS pods is:
  `(<memory-request>/<node-memory-capacity>)*<node-swap-capacity>`.
