From 66341a905ef5b3e7aea65b5d9bd1b0361b0ccc61 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Sun, 13 Nov 2005 16:07:21 -0800 Subject: [PATCH] [PATCH] Shut up per_cpu_ptr() on UP Currently per_cpu_ptr() doesn't really do anything with 'cpu' in the UP case. This is problematic in the cases where this is the only place the variable is referenced: CC kernel/workqueue.o kernel/workqueue.c: In function `current_is_keventd': kernel/workqueue.c:460: warning: unused variable `cpu' Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/linux/percpu.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/linux/percpu.h b/include/linux/percpu.h index 5451eb1..fb8d2d2 100644 --- a/include/linux/percpu.h +++ b/include/linux/percpu.h @@ -38,7 +38,7 @@ extern void free_percpu(const void *); #else /* CONFIG_SMP */ -#define per_cpu_ptr(ptr, cpu) (ptr) +#define per_cpu_ptr(ptr, cpu) ({ (void)(cpu); (ptr); }) static inline void *__alloc_percpu(size_t size, size_t align) { -- 2.7.4
