From a5dd5c117cbf620378d693963ffc42239297fac4 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Wed, 29 Sep 2010 21:02:13 +0900 Subject: [PATCH] slub: Fix signedness warnings The bit-ops routines require its arg to be a pointer to unsigned long. This leads sparse to complain about different signedness as follows: mm/slub.c:2425:49: warning: incorrect type in argument 2 (different signedness) mm/slub.c:2425:49: expected unsigned long volatile *addr mm/slub.c:2425:49: got long *map Acked-by: Christoph Lameter Acked-by: David Rientjes Signed-off-by: Namhyung Kim Signed-off-by: Pekka Enberg --- mm/slub.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) diff --git a/mm/slub.c b/mm/slub.c index aad00ba486f2..ac236b1ced16 100644 --- a/mm/slub.c +++ b/mm/slub.c @@ -2433,9 +2433,8 @@ static void list_slab_objects(struct kmem_cache *s, struct page *page, #ifdef CONFIG_SLUB_DEBUG void *addr = page_address(page); void *p; - long *map = kzalloc(BITS_TO_LONGS(page->objects) * sizeof(long), - GFP_ATOMIC); - + unsigned long *map = kzalloc(BITS_TO_LONGS(page->objects) * + sizeof(long), GFP_ATOMIC); if (!map) return; slab_err(s, page, "%s", text); @@ -3660,7 +3659,7 @@ static int add_location(struct loc_track *t, struct kmem_cache *s, static void process_slab(struct loc_track *t, struct kmem_cache *s, struct page *page, enum track_item alloc, - long *map) + unsigned long *map) { void *addr = page_address(page); void *p; -- 2.20.1
