Consider replacing with the following patch, as signals are not dealt with in
the existing code:
Description: Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. Although TASK_INTERRUPTIBLE is used in the current code,
there is no code dealing with an early return / signals_pending().
