I haven't fully read all the references, but who imposes the fact that
there's only one fault handler per device? If type1 could register one

we need this path through vfio-core?
If we could register more than one handler per device, things would become
much more simple, and the path through vfio-core would not be needed.
Hi Baolu,
Is there any restriction for having more than one handler per device?
Currently, each device could only have one fault handler. But one device
might consume multiple page tables. From this point of view, it's more
reasonable to have one handler per page table.
