The question for Christoph is what exactly is the objection here? Why we would not be using well defined ops when we know there will be more users?
The point is that there should be no more users. If you need another
Does that "No more" stops after devmem tcp?
There should be no other memory source other than the page allocator and dmabuf. If you need different life time control for your zero copy proposal don't mix that up with the contol of the memory source.
No idea how I'm mixing it up when I was explaining exactly this all along as well as that the callback (and presumably the call site in general) you was so eager to nack is used exactly to implement the life time control.
