Allow creating grant device context for use by kernel modules which
require functionality, provided by gntdev. Export symbols for dma-buf
API provided by the module.
Can you give an example of who'd be using these interfaces?
There is no use-case at the moment I can think of, but hyper dma-buf [1], [2]
I let Intel folks (CCed) to defend this patch as it was done primarily for them
and I don't use it in any of my use-cases. So, from this POV it can be dropped,
at least from this series.
