Now you're just being stubborn, Andrew ;-). The extra check does not matter much at all for most cases. What it buys us is consistent API with kfree(), more robust slab, and less bugs, no? All the super-hot paths can be fixed with __kmem_cache_free(). As an added bonus, we can remove all extra debugging checks when CONFIG_SLAB_DEBUG is disabled from __kmem_cache_free() as it will be only used in tested, known good code paths so performance for those cases will be even better! So I'll whoop up a patch soonish and send it to you. Perhaps your evil twin will apply it. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
