The only way to ensure that would be to set a strict mempolicy. But I'm not sure that's a good idea -- after all you don't want to fail an allocation in this case. But pfn_to_nid on the object like proposed by Eric should work anyways. But I'm not sure the tables used for that will be more often cache hot than the slab. -Andi - 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/
