From: Giorgi Tchankvetadze Fixes Coccinelle/coccicheck warning reported by do_div.cocci. Compared to do_div(), div64_ul() does not implicitly cast the divisor and does not unnecessarily calculate the remainder. There are no functional changes. The benefit is purely a semantic cleanup that better communicates the intent of the division and resolves the static analysis warning. Signed-off-by: Giorgi Tchankvetadze --- v2: - Add changelog text explaining that the change is a semantic cleanup with no functional impact, as requested by Mike Rapoport. --- mm/mm_init.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mm/mm_init.c b/mm/mm_init.c index f9f8e1af921cda91d812cffdad2f1a0698cfd6ac..4e0909a721d227b097653ed6aaa019960a7c3383 100644 --- a/mm/mm_init.c +++ b/mm/mm_init.c @@ -2412,7 +2412,7 @@ void *__init alloc_large_system_hash(const char *tablename, /* limit allocation size to 1/16 total memory by default */ if (max == 0) { max = ((unsigned long long)nr_all_pages << PAGE_SHIFT) >> 4; - do_div(max, bucketsize); + max = div64_ul(max, bucketsize); } max = min(max, 0x80000000ULL); --- base-commit: 6f3ed7fec72fc8979b2a8c7219c0a9fcfc8d07b5 change-id: 20260602-mm-div64-cleanup-50ad2020f2da Best regards, -- Giorgi Tchankvetadze
