A freezable kernel thread can enter frozen state during freezing by either calling try_to_freeze() or using wait_event_freezable() and its variants. So for the following snippet of code in a kernel thread loop: wait_event_interruptible_timeout(); try_to_freeze(); We can change it to a simple wait_event_freezable_timeout() and then eliminate the function calls to try_to_freeze() and freezing().
