In the cli code of info command, there is code:

	fmt.Fprintln(os.Stdout, "LxcfsEnabled: ", info.LxcfsEnabled)
	fmt.Fprintln(os.Stdout, "CriEnabled: ", info.CriEnabled)
	if info.RegistryConfig != nil && (len(info.RegistryConfig.InsecureRegistryCIDRs) > 0 || len(info.RegistryConfig.IndexConfigs) > 0) {
		fmt.Fprintln(os.Stdout, "Insecure Registries: ")

In which there is CriEnabled rather than IsCRIEnabled . So LGTM
