That is a completely illegible way of indenting this code!  There's
no visual cue when the condition stops and when the next statement
begins.  Try one of these:

			if (!folio_test_large(folio) ||
			    folio_test_hugetlb(folio) ||
			    !folio_test_lru(folio))
				goto next;

			if (!folio_test_large(folio) ||
					folio_test_hugetlb(folio) ||
					!folio_test_lru(folio))
				goto next;
