*   Added pod-level local ephemeral storage metric to the Summary API. Pod-level ephemeral storage reports the total filesystem usage for the containers and emptyDir volumes in the measured Pod. ([#55447](https://github.com/kubernetes/kubernetes/pull/55447),[ @jingxu97](https://github.com/jingxu97))...

   * stripes (much like the birthday paradox, where much fewer than anticipated birthdays are needed
   * for a pair of them to match). Please consider carefully the implications of the number of
   * stripes, the intended concurrency level, and the typical number of keys used in a {@code
   * bulkGet(keys)} operation. See <a href="http://www.mathpages.com/home/kmath199.htm">Balls in

- Changed the Pod API to support `hugepage resources` at `spec` level for pod-level resources. ([#130577](https://github.com/kubernetes/kubernetes/pull/130577), [@KevinTMtz](https://github.com/KevinTMtz)) [SIG Apps, CLI, Node, Scheduling, Storage and Testing]

- Kubelet now exposes `/debug/flags/v` to allow dynamically setting glog logging level.  For example, to change glog level to 3, you only have to send a PUT request like `curl -X PUT http://127.0.0.1:8080/debug/flags/v -d "3"`.

### Other (Cleanup or Flake)

- Client-go header logging (at verbosity levels >= 9) now masks `Authorization` header contents ([#95316](https://github.com/kubernetes/kubernetes/pull/95316), [@sfowl](https://github.com/sfowl)) [SIG API Machinery]
