Hi all,

with Daniel Vetter's and Carlos Olmedo Escobar's comments addressed, v3
(a trivial rebase) of this series is now pushed to Weston:
   f3c8336..5386898  master -> master

We can continue testing, developing, and changing the dmabuf protocol
in Weston until we are happy with it.


Thanks,
pq
