Thanks for covering DMA-BUF in phoronix right from the beginning - a tremendous job in making the framework popular amongst those not directly involved in it.
About the commeng in your last post:
There's been no signalling by the developers they are willing to make this change.
Well, I did reply, albeit a little late, to this with: https://lkml.org/lkml/2012/1/25/9.
My stand is quite clear, actually: I would really like all possible users to benefit from this framework. The original idea was also to be able to meet up at ELC and discuss (though unfortunately I won't be there, but there are enough people who can discuss it out) on how we can take this forward.
Hopefully, we should have some resolution on this sooner than later.
