For me dmabuf and cenalloc offer two different features: one is buffer
sharing (dmabuf) and one is buffer allocation (cenalloc).
You may want to use dmabuf sharing feature whithout need of the buffer
allocation feature, that is what for drm, v4l2, ION and other use
dmabuf.
In addition of dmabuf w

At present, struct device lacks a mechanism of exposing memory
access constraints for the device.
Consequently, there is also no mechanism to share these constraints
while sharing buffers using dma-buf.
If we add support for sharing such constraints, we could use that
to try to collect requiremen
