• 0bc428a57b8 kubelet: new cgroup driver: "none"
  by Akihiro Suda akihiro.suda.cz@hco.ntt.co.jp on 2019-06-02

  The "none" driver is used for running "rootless" mode on a host that does not support cgroup v2.

  This commit is specific to Usernetes and isn't going to be proposed to the Kubernetes upstream.
  So, there is no FeatureFlag for gating this driver.

• 39523fdeb00 Fix CSI initialization conflict
  by Darren Shepherd darren@rancher.com on 2019-08-30

  CSI is used by both the kubelet and kube-controller-manager. Both
  components will initialize the csiPlugin with different VolumeHost
  objects. The csiPlugin will then assign a global variable for
  the node info manager. It is then possible that the kubelet gets
  the credentials of the kube-controller-manager and that will cause
  CSI to fail.
