// traverseAndHeal - traverses on-disk data and performs healing

// has to wait until a safe point is reached, such as between scanning
// two objects.

- Introduced `v1alpha1` API for mutating admission policies, enabling extensible #     admission control via CEL expressions (KEP  3962: Mutating Admission Policies). #     To use, enable the `MutatingAdmissionPolicy` feature gate and the `admissionregistration.k8s.io/v1alpha1` #     API via `--runtime-config`. ([#127134](https://github....
