This neednt guarantee that the thread will see the stop request before
it exits the kthread_should_stop_freeze() function. There will always
be races .. So the only safe way for a thread to know whether it is time
to exit is:
while (!kthread_should_stop_freeze()) {
if (!cpu_online(home_cpu))
goto wait_to_die;
...
}
wait_to_die:
while (!kthread_should_stop()) {
/* sleep */
}
