[PATCH] mm/mmap: fix comment of unmapped_area{_topdown}

From: Vernon Yang
Date: Tue Jan 10 2023 - 10:04:12 EST


The low_limit of unmapped area information is inclusive, and the
hight_limit is not, so make the comment to correct.

Fixes: 3499a13168da ("mm/mmap: use maple tree for unmapped_area{_topdown}")
