参数：

类型参数名称
intcpu
unsigned intflags
const charnamefmt
va_listargs
687  node等于NUMA_NO_NODE
689  worker等于分配内存并置零
690  如果非worker则返回:错误号
693  kthread_init_worker(worker)
695  如果cpu大于等于0则node等于cpu_to_node(cpu)
698  task等于__kthread_create_on_node(kthread_worker_fn - kthread function to process kthread_worker*@worker_ptr: pointer to initialized kthread_worker* This function implements the main cycle of kthread worker. It processes* work_list until it is stopped with kthread_stop(), worker, node, namefmt, args)
700  如果是错误则转到:fail_task
703  如果cpu大于等于0则kthread_bind - bind a just-created kthread to a cpu
706  flags等于flags
707  task等于task
708  唤醒中断线程
709  返回:worker
711  fail_task :
712  释放内存
713  返回:错误指示
