rG62a573d9537c: vfs: retire KERN_VNODE
Summary
It got disabled in 2003:

commit acb18acfec97aa7fe26ff48f80a5c3f89c9b542d
Author: Poul-Henning Kamp <phk@FreeBSD.org>
Date:   Sun Feb 23 18:09:05 2003 +0000

    Bracket the kern.vnode sysctl in #ifdef notyet because it results
    in massive locking issues on diskless systems.

    It is also not clear that this sysctl is non-dangerous in its
    requirements for locked down memory on large RAM systems.

There does not seem to be practical use for it and the disabled routine
does not work anyway.
