ExchangeID的时候，会生成一个record，这个record中有client_id

struct nfs_client_record_t {
	int32_t cr_refcount;	
	pthread_mutex_t cr_mutex;	
	nfs_client_id_t *cr_confirmed_rec;

	uint32_t cr_pnfs_flags; 
	int cr_client_val_len;  
	char cr_client_val[];   
};

struct nfs_client_id_t {
	clientid4 cid_clientid;					// 这个结构体的标识符，可以供client快速获取这个结构体
	verifier4 cid_verifier;
	verifier4 cid_incoming_verifier;
