From 82b249361f2d1627acc7dbbdab1c80246a02fd4a Mon Sep 17 00:00:00 2001 From: Vernon Yang Date: Wed, 11 Jan 2023 21:20:36 +0800 Subject: mm/mmap: fix comment of unmapped_area{_topdown} The low_limit of unmapped area information is inclusive, and the hight_limit is not, so make symbol to be [ instead of (. And replace hight_limit to high_limit.
