函数名称：start_auth_opal_session

函数原型：static int start_auth_opal_session(struct opal_dev *dev, void *data)

返回类型：int

参数：

类型参数名称
struct opal_dev *dev
void *data
1497  session等于data
1499  keylen等于key_len
1500  err等于0
1502  key等于key
1503  hsn等于GENERIC_HOST_SESSION_NUM
1505  如果sum则err等于build_locking_user(lk_ul_user, lk_ul_user的长度, lr)
1508  否则如果who不等于OPAL_ADMIN1且非sum则err等于build_locking_user(lk_ul_user, lk_ul_user的长度, who - 1)
1511  否则memcpy(lk_ul_user, opaluid[OPAL_ADMIN1_UID], OPAL_UID_LENGTH)
1514  如果err则返回:err
1517  err等于cmd_start(dev, opaluid[OPAL_SMUID_UID], TCG Storage SSC Methods.* Derived from: TCG_Storage_Architecture_Core_Spec_v2.01_r1.00* Section: 6.3 Assigned UIDs[OPAL_STARTSESSION])
1520  add_token_u64( & err, dev, hsn)

1523  add_token_u8( & err, dev, 1)
1524  add_token_u8( & err, dev, OPAL_STARTNAME)
1525  add_token_u8( & err, dev, 0)
