From 1154fab73ccbab010cfaa272b6987c624cfd63c6 Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Mon, 1 Mar 2010 16:04:45 +1100 Subject: SLUB: Fix per-cpu merge conflict MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The slab tree adds a percpu variable usage case (commit 9dfc6e68bfe6ee452efb1a4e9ca26a9007f2b864 "SLUB: Use this_cpu operations in slub"), but the percpu tree removes the prefixing of percpu variables (commit dd17c8f72993f9461e9c19250e3f155d6d99df22 "percpu: remove per_cpu__ prefix"), thus causing the following compilation error: CC mm/slub.o mm/slub.c: In function ‘alloc_kmem_cache_cpus’: mm/slub.c:2078: error: implicit declaration of function ‘per_cpu_var’ mm/slub.c:2078: warning: assignment makes pointer from integer without a cast make[1]: *** [mm/slub.o] Error 1 Signed-off-by: Pekka Enberg --- mm/slub.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'mm') diff --git a/mm/slub.c b/mm/slub.c index 3525a4ec979..0bfd3863d52 100644 --- a/mm/slub.c +++ b/mm/slub.c @@ -2075,7 +2075,7 @@ static inline int alloc_kmem_cache_cpus(struct kmem_cache *s, gfp_t flags) * Boot time creation of the kmalloc array.
