The number of nfnetlink subsystem is small and it will remain small along time I guess. I would not spend time on such optimization. Anyway, the static subsys ID number is a good thing IMO. The floating genetlink ID allows to have out-of-tree subsystems, which is something that I don't like that. Moreover, you have to send an initial message to resolve the ID number and subscribe to possible changes in it. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
