Right. And I'm happy to go fix what remains, don't get me wrong here :-) We all know how stupid legacy code can be !
I'll try to get some patches to expose a new version of the structure sometimes in the upcoming week or two (we'll see what time permits) and then see about fixing X drivers that need fixing, though hopefully with pci-rework being upstream now, that shouldn't be many.
The main issue is directfb. I hope they'll catch up with the new ioctls.
Ben.
