Under certain circumstances we could leak elements which were moved to the local "to_free" list. The damage is limited since I can't find any users here. Cc: stable-rt@xxxxxxxxxxxxxxx Signed-off-by: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx> --- Jesper: There are no users of kmem_cache_alloc_bulk() and kfree_bulk(). Only kmem_cache_free_bulk() is used since it was introduced. Do you think that it would make sense to remove those? mm/slub.c | 1 + 1 file changed, 1 insertion(+) diff --git a/mm/slub.c b/mm/slub.c index ffd2fa0f415e..9053e929ce9d 100644 --- a/mm/slub.c +++ b/mm/slub.c @@ -3240,6 +3240,7 @@ int kmem_cache_alloc_bulk(struct kmem_cache *s, gfp_t flags, size_t size, return i; error: local_irq_enable(); + free_delayed(&to_free); slab_post_alloc_hook(s, flags, i, p); __kmem_cache_free_bulk(s, i, p); return 0; -- 2.15.1 -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
