AIUI, this affects what the user sees in /proc/<pid>/maps, right? Previously a memory range could be clearly associated with a specific vfio device, now, only for vfio-pci devices, I think the range is associated to a nondescript dmabuf.

IIRC there is a way to attach a string to the inode that lsof can display, if we do that right it should be good enough.
