Subject: wait_queue's
Date: Tue, 03 Dec 2002 10:01:58 +0200	[thread overview]
Message-ID: <3DEC64F6.4050003@tlabs.ac.za> (raw)

Hello

I'm busy writing a device driver.
This device driver exports one char device.

Now the problem it that when 2 programs try to write to this device at 
the same time...
Well it works but they don't get queue fairly.

Both processes write's get blocked.. But for a long time in a row only 
one seem to write and the otherone stays block.
I think the problem is that the kernel wait queue is a LIFO structure 
and not a FIFO

Anyway in which I could change it to a FIFO? or any other ideas?

Thanks
-Heinrich
