Date: Thu, 23 Oct 2025 09:47:32 +0800 [thread overview]
Message-ID: <20251023014732.73721-1-leon.hwang@linux.dev> (raw)
This reverts commit a584c7734a4dd050451fcdd65c66317e15660e81 to avoid
the build error:
map_hugetlb.c: In function 'main':
map_hugetlb.c:79:25: warning: implicit declaration of function 'default_huge_page_size' [-Wimplicit-function-declaration]
79 | hugepage_size = default_huge_page_size();
Signed-off-by: Leon Hwang <leon.hwang@linux.dev>
