Please consider applying.
Use msleep_interruptible() instead of schedule_timeout() to
guarantee consistent timing regardless of HZ value. schedule_timeout(1) will
vary between 10 and 1 milliseconds, depending on the value of HZ (100 or 1000
respectively). For consistent behavior, msleep_interruptible() should be used.
