This is not needed anmore. kthread_run guarantees that the newly
creates thread is run before returning to the caller.

I don't think you need this one either. You can use wake_up_process
on the task_struct pointer instead.

Btw, it might make sense to remove sync_thread and just call the
master and backup threads directly.

Why can't this be initialized at compile time by:
static struct sockaddr_in mcast_addr = {
.sin_family = AF_INET,
.sin_port = htons(IP_VS_SYNC_PORT),
.sin_addr.s_addr = htonl(IP_VS_SYNC_GROUP),
}
(the hton* might need __constant_hton* also I'm not sure without trying)
