关于struct t10_wwn结构体

zbs7260799

struct t10_wwn {
        char vendor[8];
        char model[16];
        char revision[4];
        char unit_serial[INQUIRY_VPD_SERIAL_LEN];
        spinlock_t t10_vpd_lock;
        struct se_subsystem_dev *t10_sub_dev;
        struct config_group t10_wwn_group;
        struct list_head t10_vpd_list;
} ____cacheline_aligned;

请问这个结构体里面哪一项表示硬盘的wwn.
shell界面下我们在/dev/disk/by-id和哪个结构体是对应的,谢谢.
