True. Not that the intent is to kill kernel space callers of setsockopt, as I plan to remove the set_fs address space override used for it. So if always pulling in sctp is not an option for the DLM maintainers we'd have to do tricks using symbol_get() or similar. The same would also apply for ipv6, although I'm not sure how common modular ipv6 is in practice.
