No, that testing was with the whole series including the parts where you synchronized intel with radeon (iirc).
Although it might if lucky, I noticed that I missed a int to long conversion, which resulted in a success being
reported as error, disabling graphics acceleration entirely.

The series here simply convert the drivers to a common fence infrastructure, but shouldn't cause any regressions
or any major behavioral changes. A separate series is needed to make intel and radeon synchronized,
and for that series the support on the intel side is a hack. It should be possible to get the the radeon/nouveau
changes upstreamed, but this conversion is required for that.
