Subject: [PATCH] mm: page_alloc: fix building error on -Werror=array-compare
|
|
|
|
Arthur Marsh reported we would hit the error below when building kernel
|
|
with gcc-12:
|
|
|
|
CC mm/page_alloc.o
|
|
mm/page_alloc.c: In function `mem_init_print_info':
|
|
mm/page_alloc.c:8173:27: error: comparison between two arrays [-Werror=array-compare]
|
|
8173 | if (start <= pos && pos < end && size > adj) \
|
|
|
|
|
|
|
In C++20, the comparision between arrays should be warned.
