libnvdimm, namespace: do not delete namespace-id 0
Given that the naming of pmem devices changes from the pmemX form to the pmemX.Y form when namespace id is greater than 0, arrange for namespaces with id-0 to be exempt from deletion. Otherwise a simple reconfiguration of an existing namespace to a new mode results in a name change of the resulting block device: # ndctl list --namespace=namespace1.0 { "dev":"namespace1.0", "mode":"raw", "size":2147483648, "uuid":"3dadf3dc-89b9-4b24-b20e-abc8a4707ce3", "blockdev":"pmem1" } # ndctl create-namespace --reconfig=namespace1.0 --mode=memory --force { "dev":"namespace1.1", "mode":"memory", "size":2111832064, "uuid":"7b4a6341-7318-4219-a02c-fb57c0bbf613", "blockdev":"pmem1.1" } This change does require tooling changes to explicitly look for namespaceX.0 if the seed has already advanced to another namespace.
