* Fix a bug where kubelet would not retry pod sandbox creation when the restart policy of the pod is Never ([#79451](https://github.com/kubernetes/kubernetes/pull/79451), [@yujuhong](https://github.com/yujuhong))

- Remove ready file and its directory (which is created during volume SetUp) during emptyDir volume TearDown. ([#95770](https://github.com/kubernetes/kubernetes/pull/95770), [@jingxu97](https://github.com/jingxu97)) [SIG Storage]

  
  kubelet also ignores an error during opening `/dev/kmsg`.
  This feature gate also allows kube-proxy to ignore an error during setting `RLIMIT_NOFILE`.
  

- Disabled `LocalStorageCapacityIsolation` feature gate is honored during scheduling. ([#96092](https://github.com/kubernetes/kubernetes/pull/96092), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling]
- Do not fail sorting empty elements. ([#94666](https://github.com/kubernetes/kubernetes/pull/94666), [@soltysh](https://github.com/soltysh)) [SIG CLI]

If the list request contained label or field selectors, then the number of remaining items is unknown and the field will be left unset and omitted during serialization. If the list is complete (either because it is not chunking or because this is the last chunk), then there are no more remaining items and this field will be left unset and omitted during serialization. Servers older than v1.15 do not set this field. The intended use of the remainingItemCount is *estimating* the size of a collection....

installation, upgrade and configuration even more robust has been a major focus for this cycle for SIG Cluster Lifecycle (see the May 6, 2019 [Community Update](https://docs.google.com/presentation/d/1QUOsQxfEfHlMq4lPjlK2ewQHsr9peEKymDw5_XwZm8Q/edit?usp=sharing)). Bug fixes across bare metal tooling and production-ready user stories, such as the high availability use cases have been given priority for 1.15.
