在include/linux/kthread.h里有如下的宏定义，用来创建和唤醒一个线程
/** 18 * kthread_run – create and wake a thread. 19 * @threadfn: the function to run until signal_pending(current). 20 * @data: data ptr for @threadfn. 21 * @namefmt: printf-style name for the thread. 22 * 23 * Description: Convenient wrapper for kthread_create() followed by 24 * wake_up_process(). Returns the kthread or ERR_PTR(-ENOMEM). 25 */ 26#define kthread_run(threadfn, data, namefmt, …) \ 27({ \ 28 struct task_struct *__k \ 29 = kthread_create(threadfn, data, namefmt, ## __VA_ARGS__); \ 30 if (!IS_ERR(__k)) \ 31 wake_up_process(__k); \ 32 __k; \ 33})
我要扼住命运的咽喉。
