kthread_run

创建内核线程的方法 kthread_run，示例如下：

//线程执行函数

static int kthread_loop(void* param)

{

int loopVal = 0;

printk(KERN_INFO "start loop\n");

while (1)

{

//加入退出判断

}

printk(KERN_INFO "stop loop\n");

return 0;

}

//创建线程并唤新线程

struct task_struct *loop_task = kthread_run(kthread_loop, NULL, "loop");

if (IS_ERR(loop_task)) 

{

printk(KERN_ERR "print loop: unable to create kernel thread: %ld\n",

PTR_ERR(loop_task));

}

//如果有兴趣还可以将其绑定到指定的CPU上

set_cpus_allowed(loop_task, cpumask_of_cpu(15));
