If you disable them then we are fine. I think the main "bug" is that we create the caches with ARCH_KMALLOC_MINALIGN in kmem_cache_init but allow debug options on them. It seemss that we need to be able to disable debugging from kmem_cache_init. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
