No, this patch is an independent one. The objective is to behavior the same when @range->start + @range->len overflows when @range->len is not default value (U64MAX). With the trim range patch reverted, we should still detect overflow and return -EINVAL to meet the new generic/260 check. So please still include this patch. Thanks, Qu
