Date: Wed, 18 Jul 2007 17:42:11 +0200 From: Johannes Berg <johannes@...solutions.net> To: Christoph Lameter <clameter@....com> Cc: linux-kernel <linux-kernel@...r.kernel.org> Subject: [RFC] fix slub krealloc() Commit ef2ad80c7d255ed0449eda947c2d700635b7e0f5 breaks krealloc(NULL, ...) badly, it BUG_ON()s. This patch fixes it but the fix should probably be in mm/util.c because the documentation says that krealloc(NULL, x, gfp) is equivalent to kmalloc(x, gfp) and that's not true any more even after this patch when you do krealloc(NULL, 0, gfp) johannes --- mm/slub.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- wireless-dev.orig/mm/slub.c 2007-07-18 16:25:11.809440194 +0200 +++ wireless-dev/mm/slub.c 2007-07-18 16:25:22.809440194 +0200 @@ -2394,7 +2394,7 @@ size_t ksize(const void *object) struct page *page; struct kmem_cache *s; - if (object == ZERO_SIZE_PTR) + if (object == ZERO_SIZE_PTR || !object) return 0; page = get_object_page(object); - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
