It's also another nasty pseudo C prototype. I know we do this sort of thing for container_of et al, but I don't really think we want to extend it. Why not make the interface take a pointer to the embedding structure and one to the rcu_head ... that way all pointer mathematics can be contained inside the RCU routines.
