Recently the k8s.io/mount-utils package added more runtime dectection. When creating a new Mounter, the detect is run every time. This is unfortunate, as it logs a message like the following: ``` mount_linux.go:283] Detected umount with safe 'not mounted' behavior ``` This message might be useful, so it probably good to keep it. In Ceph-CSI there are various locations where Mounter instances are created. Moving that to the DefaultNodeServer type reduces it to a single place. Some utility functions need to accept the additional parameter too, so that has been modified as well. See-also: kubernetes/kubernetes#109676 Signed-off-by: Niels de Vos <ndevos@redhat.com>
