func main() {
	go setup()
	for g == nil {

<p>
Even if <code>main</code> observes <code>g != nil</code> and exits its loop,
there is no guarantee that it will observe the initialized
value for <code>g.msg</code>.

<p>
In all these examples, the solution is the same:
use explicit synchronization.

- Fixes a bug in the `k8s.io/cloud-provider/service`  controller, it may panic when a service is updated because the event recorder was used before it was initialized. All cloud providers should using the `v1.31.0` cloud provider service controller must ensure that the controllers is initialized before the informer start to process events or update it to the version 1.32.0.

Kubernetes with a different admission-control flag on API server. ([#58080](https://github.com/kubernetes/kubernetes/pull/58080), [@simonferquel](https://github.com/simonferquel))

* Alpha Initializers have been removed from kubeadm admission control.  Kubeadm users who still want to use Initializers can use apiServerExtraArgs through the kubeadm config file to enable it when booting up the cluster.
