Even for nodes that have a BlockBackend attached, bdrv_get_parent_name() can return NULL if the BB is anonymous (e.g. it belongs to a block job or a device that was created with a drive=<node-name> option). Remove the information from the error message. The user probably knows already why the node is still in use. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
