函数名称：setup_locking_range

函数原型：static int setup_locking_range(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
1349  setup等于data
1353  lr等于lr
1354  err等于build_locking_range(uid, uid的长度, lr)
1355  如果err则返回:err
1358  如果lr恒等于0则err等于enable_global_lr(dev, uid, setup)
1360  否则
1361  err等于cmd_start(dev, uid, TCG Storage SSC Methods.* Derived from: TCG_Storage_Architecture_Core_Spec_v2.01_r1.00* Section: 6.3 Assigned UIDs[OPAL_SET])
