Thanks for your reply, I can understand more 'acks' will be better, but there is no comments object to this patch or any 'NAK' common for more then 3 months, maintainers should move to next step.

I expect you to poke relevant driver maintainers directly for these acks. That was the purpose of my mail. All communication going through maintainers, being exclusively orchestrated by maintainers, just doesn't scale. So not an option for a big subsystem like drivers/gpu. Hope that makes it clear. For merging Sandy has commit rights to drm-misc, so that's not the problem.
