This is a clone of issue OCPBUGS-8683. The following is the description of the original issue:
—
Clone of OCPBUGS-7906, but for all the other CSI drivers and operators than shared resource. All Pods / containers that are part of the OCP platform should run on dedicated "management" CPUs (if configured). I.e. they should have annotation 'target.workload.openshift.io/management:{"effect": "PreferredDuringScheduling"}' .

Enhancement: https://github.com/openshift/enhancements/blob/master/enhancements/workload-partitioning/management-workload-partitioning.md

So far nobody ran our cloud CSI drivers with CPU pinning enabled, so this bug is a low prio. I checked LSO, it already has correct CPU pinning in all Pods, e.g. here.
