I guess you dont need to use skb itself to hold all your states ? I understand its convenient for you, but I believe its worth the pain to use only one pointer to a (small) object where you put all your stuff. Some machines alloc/free millions of skbs per second. If/when most skb uses are for userspace zero-copy buffers we can embbed your small object in skb itself ;) -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
