| |
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.
Fixes: 3499a13168da ("mm/mmap: use maple tree for unmapped_area{_topdown}") Signed-off-by: Vernon Yang <vernon2gm@gmail.com> ---
Changes since v1: - replace hight_limit to high_limit.
