- * because of that generic code limitation, MAP_FIXED mapping cannot
- * "convert" back a slice with no VMAs to the standard page size, only
- * get_unmapped_area() can. It would be possible to fix it here but I
- * prefer working on fixing the generic code instead.
- *
- * WARNING: This will not work if hugetlbfs isn't enabled since the
- * generic code will redefine that function as 0 in that. This is ok
- * for now as we only use slices with hugetlbfs enabled. This should
- * be fixed as the generic code gets fixed.
