The
CSIVolumestruct has references to allocations that are "denormalized"; we don't store them on theCSIVolumestruct but hydrate them on read. Tests detecting potential state store corruptions (ref #16257) found two locations where we're not copying the volume before denormalizing:There are no known user-visible problems associated with these bugs but both have the potential of mutating volume claims outside of a FSM transaction. This changeset also cleans up state mutations in some CSI tests so as to avoid having working tests cover up potential future bugs.
