What I was _testing_ had this hunk in that I neglected to commit to git
before running format-patch:

@@ -784,6 +784,7 @@ static void hugetlbfs_init_regular_inode(struct inode *inode)
        inode->i_op = &hugetlbfs_inode_operations;
        inode->i_fop = &hugetlbfs_file_operations;
        mapping_set_folio_order_range(inode->i_mapping, order, order);
+       mapping_set_authoritative(inode->i_mapping);
 }
