The maintainers file is fine to have a new stanza:

+IOMMU FD
+M: Jason Gunthorpe <jgg@nvidia.com>
+M: Kevin Tian <kevin.tian@intel.com>
+L: iommu@lists.linux.dev
+S: Maintained
+F: Documentation/userspace-api/iommufd.rst
+F: drivers/iommu/iommufd/
+F: include/uapi/linux/iommufd.h
+F: include/linux/iommufd.h

It says who to send patches to for review..
