Thanks a lot of picking this up.

I'm aware of an issue with patch 9 as I can see requests with perf 
queries being preempted. Looking into that, but not quite there yet.


I think there is a dependency issue with patch 8. We also use 
cliprects_ptr for fences.

If we start reusing it for extended parameters, we need to make fences 
the first extended param.
