 If you enable the `PodOverhead` [feature gate](/docs/reference/command-line-tools-reference/feature-gates/), and define a RuntimeClass with [Pod overhead](/docs/concepts/scheduling-eviction/pod-overhead/) configured, this admission controller checks incoming
 Pods. When enabled, this admission controller rejects any Pod create requests that have the overhead already set.
