## Résumé

* Add a flag allowing contention profiling of the API server ([#36756](https://github.com/kubernetes/kubernetes/pull/36756), [@gmarek](https://github.com/gmarek))

As an alpha feature, Kubernetes v1.22 can use the cgroups v2 API to control memory allocation and isolation. This feature is designed to improve workload and node availability when there is contention for memory resources.

### API changes and improvements for ephemeral containers

        `tf.data.Dataset.enumerate`.
    *   Promoting `tf.data.experimental.unbatch` to core as
        `tf.data.Dataset.unbatch`.
    *   Adds option for introducing slack in the pipeline to reduce CPU
        contention, via `tf.data.Options().experimental_slack = True`
    *   Added experimental support for parallel batching to `batch()` and
        `padded_batch()`. This functionality can be enabled through
        `tf.data.Options()`.

The connection lock is never held while doing I/O (even closing a socket) to prevent contention.

[GC guide](/doc/gc-guide#Linux_transparent_huge_pages), or switch to a Linux
distribution that disables transparent huge pages altogether.

Go 1.22 added contention on runtime-internal locks to the [`mutex`
profile](/pkg/runtime/pprof#Profile). Contention on these locks is always
reported at `runtime._LostContendedRuntimeLock`. Complete stack traces of
runtime locks can be enabled with the [`runtimecontentionstacks`

    Castle is great! But it's a large dependency (6.5 MiB) and its security provider feature
    impacts VM-wide behavior.

 *  New: Reduce contention for applications that make a very high number of concurrent requests.
    Previously OkHttp used its connection pool as a lock when making changes to connections and

* Fix comment and optimize code ([#38084](https://github.com/kubernetes/kubernetes/pull/38084), [@tanshanshan](https://github.com/tanshanshan))
* Add flag to enable contention profiling in scheduler. ([#37357](https://github.com/kubernetes/kubernetes/pull/37357), [@gmarek](https://github.com/gmarek))

- Changed docs for `--contention-profiling` flag to reflect it performed block profiling ([#114490](https://github.com/kubernetes/kubernetes/pull/114490), [@MadhavJivrajani](https://github.com/MadhavJivrajani))

    * cAdvisor: Fix brtfs filesystem discovery
    * cAdvisor: Fix race condition with AllDockerContainers
    * cAdvisor: Don't watch .mount cgroups
    * cAdvisor: Reduce lock contention during list containers
* Promote ScheduleDaemonSetPods by default scheduler to beta ([#67899](https://github.com/kubernetes/kubernetes/pull/67899), [@ravisantoshgudimetla](https://github.com/ravisantoshgudimetla))
