SubjectRE: [PATCH 7/7] iommu: Add iommu_domain::domain_ops

What is the criteria about whether an op should be iommu_ops or domain_ops
when it requires both domain and device pointers like above two (and future
PASID-based attach)?

Other examples include:
@apply_resv_region
@is_attach_deferred

Thanks
Kevin
