From 16855f878d7127a8bb3925753463485f3071ad76 Mon Sep 17 00:00:00 2001 From: Hiroshi Shimamoto Date: Mon, 8 Dec 2008 19:18:38 -0800 Subject: [PATCH] x86: uaccess: return value of __{get|put}_user() can be int Impact: cleanup The type of return value of __{get|put}_user() can be int. There is no user to refer the return value of __{get|put}_user() as long. This reduces code size a bit on 64-bit. $ size vmlinux.* text data bss dec hex filename 4509265 479988 673588 5662841 566879 vmlinux.new 4511462 479988 673588 5665038 56710e vmlinux.old Signed-off-by: Hiroshi Shimamoto Signed-off-by: Ingo Molnar --- arch/x86/include/asm/uaccess.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/x86/include/asm/uaccess.h b/arch/x86/include/asm/uaccess.h index 35c54921b2e4..580c3ee6c58c 100644 --- a/arch/x86/include/asm/uaccess.h +++ b/arch/x86/include/asm/uaccess.h @@ -350,14 +350,14 @@ do { \ #define __put_user_nocheck(x, ptr, size) \ ({ \ - long __pu_err; \ + int __pu_err; \ __put_user_size((x), (ptr), (size), __pu_err, -EFAULT); \ __pu_err; \ }) #define __get_user_nocheck(x, ptr, size) \ ({ \ - long __gu_err; \ + int __gu_err; \ unsigned long __gu_val; \ __get_user_size(__gu_val, (ptr), (size), __gu_err, -EFAULT); \ (x) = (__force __typeof__(*(ptr)))__gu_val; \ -- 2.39.5
