task queues and SMP

Hi,

I am facing some problem running task queues on an SMP machine. I am using tq_schedule queue. I queue the task in interrupt context.

temp_end_io(.....)

{
	if (uptodate == 0) // on error
	{
		if (!in_interrupt())
			generic_make_request
		else
		{
			// add buffer head to linked list
			schedule_task(tq_ownstruct);
		}
	}
}

tq_ownstruct.routine = xyz;

xyz()

{
	// pop from list
	// call generic_make_request
}

Somehow all bufferheads are not scheduled. Is there a problem b'coz I am using a global linked list ??

Any know problem task queues and SMP machines ??

Thanks and Regards,
David Anderson
