[PATCH v2 0/6] IOMMUFD: Deliver IO page faults to user space

This is the right way to approach it, and more broadly this shouldn't
be an iommufd specific thing. Kernel drivers will also need to create
fault capable PAGING iommu domains.

Are you suggesting a common interface used by both iommufd and
kernel drivers?
