Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(), vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically. Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function. All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference. PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.
