函数名称：padata_reorder

函数原型：static void padata_reorder(struct parallel_data *pd)

返回类型：void

参数：

类型参数名称
struct parallel_data *pd
216  pinst等于pinst
232  如果非spin_trylock_bh( & lock)则返回
235  当1循环
236  padata等于padata_find_next - Find the next object that needs serialization
243  如果非padata则退出
246  cb_cpu等于cb_cpu
247  squeue等于per_cpu_ptr(squeue, cb_cpu)
249  加自旋锁
250  添加链表项
251  自旋锁解锁
253  queue_work_on - queue work on specific cpu*@cpu: CPU number to execute work on*@wq: workqueue to use*@work: work to queue* We queue the work to a specific CPU, the caller must ensure it* can't go away.
256  spin_unlock_bh( & lock)
266  smp_mb()
268  next_queue等于per_cpu_ptr(pqueue, cpu)
269  如果非链表为空且padata_find_next - Find the next object that needs serialization则queue_work - queue work on a workqueue*@wq: workqueue to use*@work: work to queue* Returns %false if @work was already on a queue, %true otherwise.* We queue the work to the CPU on which it was submitted, but if the CPU dies
