From 48c232395431c23d35cf3b4c5a090bd793316578 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Tue, 6 Feb 2018 15:36:48 -0800 Subject: kasan: remove redundant initialization of variable 'real_size' Variable real_size is initialized with a value that is never read, it is re-assigned a new value later on, hence the initialization is redundant and can be removed. Cleans up clang warning: lib/test_kasan.c:422:21: warning: Value stored to 'real_size' during its initialization is never read Link: http://lkml.kernel.org/r/20180206144950.32457-1-colin.king@canonical.com Signed-off-by: Colin Ian King Acked-by: Andrey Ryabinin Reviewed-by: Andrew Morton Cc: Alexander Potapenko Cc: Dmitry Vyukov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- lib/test_kasan.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/test_kasan.c b/lib/test_kasan.c index a808d81..98854a6 100644 --- a/lib/test_kasan.c +++ b/lib/test_kasan.c @@ -419,7 +419,7 @@ static noinline void __init kasan_stack_oob(void) static noinline void __init ksize_unpoisons_memory(void) { char *ptr; - size_t size = 123, real_size = size; + size_t size = 123, real_size; pr_info("ksize() unpoisons the whole allocated chunk\n"); ptr = kmalloc(size, GFP_KERNEL); -- cgit v1.1
