Includes this bit: >> Why 64-bit math here, but 128 bit math in the region_add path? > > Hm. Good question. It has been copied from the common VFIO code where it was since 7532d3cbf1, back those days I did not even think of VFIO devices hot(un)plugging so > region_del() was never executed so this seems to be a bug there and here. Yet another patch is coming then There are other things that aren't nearly as troublesome but it certainly feels like another round of patches are forthcoming. I didn't get a feeling from the patchset that this was functional, no Tested-by: or Acked-by: either.
