Then its racy, unless you also changed the way your worker threads exit.
By the time kthread_run() returns, child thread can already be gone.
This is why I use kthread_create() : to be able to get_task_struct() so that task_struct cannot disappear, even if the child exits really fast :
int worker(void *arg) { return 0; }
