This was never discussed with anybody Nouveau related and we would have NACKed this change immediately. We have a better workaround, which makes it actually work with Nouveau. No idea why the comment mentions the Nvidia driver and assumes it gives any weight to the reasoning.... we don't care about out of tree drivers. Nouveau does support RTD3, but we had some issues with that. And we even have a better fix for this issue. Also, can we _please_ do it in a way worthy of an upstream community the next time? If some distribution feels like they have to please companies not wanting to be part of the linux community, please do so downstream and don't try to push something like this upstream.
