	// Past a certain chunk size it is counterproductive to use
	// larger chunks as the source of the write, as when the source
	// is too large we are basically just thrashing the CPU D-cache.
	// So if the result length is larger than an empirically-found
	// limit (8KB), we stop growing the source string once the limit
	// is reached and keep reusing the same source string - that

- Fixed a bug whereby the allocation of reusable CPUs and devices was not being honored when the TopologyManager was enabled ([#93189](https://github.com/kubernetes/kubernetes/pull/93189), [@klueska](https://github.com/klueska)) [SIG Node]

  * There are known bugs that result in errors when querying Kubelet's stats summary API. We expect to fix them in v1.8.1.

#### kubelet

* [alpha] Kubelet now supports alternative container-level CPU affinity policies by using the new CPU manager. ([#375](https://github.com/kubernetes/enhancements/issues/375), [@sjenning](https://github.com/sjenning), [@ConnorDoyle](https://github.com/ConnorDoyle))
