From: Nishanth Aravamudan <[email protected]>
Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. Although TASK_INTERRUPTIBLE is used in the
original code, schedule_timeout() return conditions for such a state
are not checked appropriately; therefore, TASK_UNINTERRUPTIBLE should
be ok (and, hence, msleep()).
