- Fixed a 1.30.0 regression in OpenAPI descriptions of the `imagePullSecrets` and 
  `hostAliases` fields to mark the fields used as keys in those lists as either defaulted
  or required. ([#124553](https://github.com/kubernetes/kubernetes/pull/124553), [@pmalek](https://github.com/pmalek))

var s2 = s1                    // s2 stores the slice descriptor of s1
s1 = s1[:1]                    // s1's length is 1 but it still shares its underlying array with s2
s2[0] = 42                     // setting s2[0] changes s1[0] as well
fmt.Println(s1, s2)            // prints [42] [42 2 3]

var m1 = make(map[string]int)
var m2 = m1                    // m2 stores the map descriptor of m1

          The issue can be identified by using the node problem detector.

        - File descriptor leak on init/control.
          ([#275](https://github.com/containerd/containerd/issues/275))
