A bug in the queue_task routine...

The Tasks Queued are scheduled in the reverse order
of queueing. ( The task Queue is being handled as a
Stack ).

The queue_task() routine in include/linux/tqueue.h
queues the task at the head of the list.

The run_queue_task() routine picks up the tasks
from the head of the queue.

So the task that is queued later gets scheduled first.
This is LIFO functionality.
But I think the functionality should be FIFO.

Is this the intended behaviour.?
Any particular reason for this kind of behaviour.?
