Just for the archives, because I guess my solution won't fit your needs
if you use kernel 2.4.
Using kernel 2.6, there is a quite simple API available for that:
static struct task_struct *my_thread = NULL;
static int thread_task(void *arg)
{
while(!kthread_should_stop()) {
...
msleep_interruptible(2000);
}
}
static int __init my_module_init() {
my_thread = kthread_run(thread_task, th, "kmyname");
if (my_thread == ERR_PTR(-ENOMEM)) {
...
my_thread = NULL;
}
}
static int __init my_module_exit() {
if (my_thread != NULL)
kthread_stop(my_thread);
}
