- Move from the old github.com/golang/glog to k8s.io/klog - klog as explicit InitFlags() so we add them as necessary - we update the other repositories that we vendor that made a similar change from glog to klog * github.com/kubernetes/repo-infra * k8s.io/gengo/ * k8s.io/kube-openapi/ * github.com/google/cadvisor - Entirely remove all references to glog - Fix some tests by explicit InitFlags in their init() methods Change-Id: I92db545ff36fcec83afe98f550c9e630098b3135
