It may be true that SLAB uses a bit only internally (and already protects it with a BUG_ON() in __kmem_cache_create()) but that doesn't mean other implementations can't use such a flag that would be a no-op on another allocator. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
