-/* Very special super-nasty workaround here:
- *
- * Before 2.6.19, nlmsg_multicast() lacked a 'flags' parameter. We work
- * around that in our <net/netlink.h> replacement, so that nlmsg_multicast
- * is a macro that expands to rpl_nlmsg_multicast, which in turn has the
- * 'flags' parameter.
- *
- * However, also before 2.6.19, <net/genetlink.h> contains an inline definition
- * of genlmsg_multicast() that, of course, calls it without the 'flags'
- * parameter. This causes a build failure.
- *
- * This works around the problem by temporarily renaming both nlmsg_multicast
- * and genlmsg_multicast with a "busted_" prefix. (Nothing actually defines
- * busted_nlmsg_multicast(), so if anything actually tries to call it, then
- * we'll get a link error.)
