This way you would also be able to construct different handles (like GEM obj or V4L2 buffers) from the same backing nvhost object. Note that I'm not sure how useful this would be, but it seems like a reasonable design to me being able to do so.
Wouldn't that be useful for sharing buffers between DRM and V4L2 using dma-buf? I'm not very familiar with how exactly importing and exporting work with dma-buf, so maybe I need to read up some more.
I would still preserve the dma-buf support, for exactly this purpose.
