Hmm. Will kthread_should_stop() be set if it should really exit? If so, 
perhaps you can just remove the signal_pending() check. Otherwise, you'd want 
to change the signal_pending() test to something like the "if 
(signal_pending() && !try_to_freeze())" to avoid any possibility of a race. 
(In this case, you should be able to remove the try_to_freeze() from above).
