Module_license ("Dual BSD/GPL");//Follow the Linux protocol

static int hello_init (void)

{

PRINTK (Kern_alert "Hello, world\n");//Print driver information

return 0;

}

static void Hello_exit (void)

{

PRINTK (Kern_alert "Goodbye, cruel world\n");//Print driver information

}

Module_init (hello_init);//Print driver initialization information

Module_exit (hello_exit);//print driver end information
