Hi Terrence, would it be possible for you to pull v3 to test on?
https://github.com/nicolinc/iommufd/commits/dev/vfio_pin_pages-v3

They are basically same but there's a new DIV_ROUND_UP change,
which shouldn't result in any functional difference, IMHO. If
v3 passes, I can simply add your Tested-by when I respin it.

Thanks
Nic
