In comparison this is the unpatched 19.x originally (10 sec):

-> 12466 (any) ioctl calls
-> 3111 DRM_IOCTL_RADEON_GEM_CREATE
-> 3112 DRM_IOCTL_GEM_CLOSE

^^Sorry these values were bad, it is not this much and I don't know how I
measured this back then but I cannot do it anymore.


Actually it is not that easy to find the "more minor" issue, but I still feel
it is there. The only way for finding it is to bisect in this way:

-> bisect ...
-> apply patches of Marek
-> See if result has 7-8 CREATE calls or a bit more
-> stash away patches
-> bisect ...

Only this way it is properly measurable because "measuring" without the patch
in place is much harder to do by naked eye.
