in mind. It would be unfortunate if restricting its use to only GPL-licensed modules caused dma-buf adoption to be limited.
You appear confused. I'll say this again is my lawyer advises me that for the benefit of any future enforcement actions I should remind people each time it comes up.
For a Linux kernel containing any code I own the code is under the GNU public license v2 (in some cases or later), I have never given permission for that code to be used as part of a combined or derivative work which contains binary chunks. I have never said that modules are somehow magically outside the GPL and I am doubtful that in most cases a work containing binary modules for a Linux kernel is compatible with the licensing, although I accept there may be some cases that it is.
