not really. Below the users of the struct iommu_user_data in my current iommufd_nesting branch. Only the domain_alloc_user op has type as there can be multiple vendor specific alloc data types. Basically, I'm ok to make the change you suggested, just not sure if it is good to add type as it is only needed by one path.

I don't think we should ever have an opaque data blob without a type tag..
