Hm. Do you think that all drivers should implement a ->request()
callback?
@Tony: What do you think, does vfio_ap need something like this?
BTW how is this supposed to work in a setup where the one parent
has may children (like vfio_ap or the gpu slice and dice usecases).
After giving this some thought I'm under the impression, I don't
get the full picture yet.
Eric Farman touched base with me on Friday to discuss this, but
I was on my way out the door for an appointment. He is off this
week; so, the bottom line for me is that I don't have even a
piece of the picture here and therefore don't have enough
info to speculate on whether vfio_ap needs something like this.
