函数原型：static int opal_enable_disable_shadow_mbr(struct opal_dev *dev, struct opal_mbr_data *opal_mbr)

返回类型：int

参数：

类型参数名称
struct opal_dev *dev
struct opal_mbr_data *opal_mbr
2203  enable_disable等于如果enable_disable恒等于OPAL_MBR_ENABLE则 Boolean 否则OPAL_FALSE
2206  const struct opal_step mbr_steps[] = {{start_admin1LSP_opal_session, & key}, {set_mbr_done, & enable_disable}, {end_opal_session, }, {start_admin1LSP_opal_session, & key}, {set_mbr_enable_disable, & enable_disable}, {end_opal_session, }}
2216  如果enable_disable不等于OPAL_MBR_ENABLE且enable_disable不等于OPAL_MBR_DISABLE则返回:负EINVAL
2220  mutex_lock( & dev_lock)
2221  setup_opal_dev(dev)
2222  ret等于execute_steps(dev, mbr_steps, ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(mbr_steps))
2223  mutex_unlock - release the mutex*@lock: the mutex to be released* Unlock a mutex that has been locked by this task previously.* This function must not be used in interrupt context. Unlocking* of a not locked mutex is not allowed.
