Description Jan Safranek 2022-02-21 16:46:25 UTC

Kubelet sometimes fails unmounting a volume with "wait: no child processes", because unmount was too fast.

Details: https://github.com/kubernetes/kubernetes/issues/103753

This has been fixed in 4.10 in https://github.com/openshift/aws-efs-csi-driver/pull/9
