orodos (2726891) writes "[Nvidia]'s Robert Morell submitted a patch to remove the GPL license from the dma buffer interface in the Linux kernel so it can be used in Nvidia's driver. Not everybody is happy, especially Alan Cox, who has been involved in Linux development since 1991 and was most influential when he maintained the version 2.2 of the Linux kernel.
Cox unmistakably told Morell that he and "many others" are not happy with the idea of combining proprietary and GPL code. Cox declined to accept Morell's patch. The argument appears to be stuck at this time as words started flying and Cox told Morell that a patch acceptance will have to get the confirmation of all rightsholders of the code, some of apparently include Red Hat and Intel. The developer left Morell with the thought to get those confirmations via attorneys." Link to Original Source
