>Description:

The pfil(9) man page documents the functions pfil_head_register() and
pfil_head_unregister() which don't actually exist in the kernel.

Apparently they were replaced by something else in this commit:

Author: rmind <rmind@NetBSD.org>
Date:   Sat Jun 29 21:06:57 2013 +0000

    - Rewrite parts of pfil(9): use array to store hooks and thus be more cache
      friendly (there are only few hooks in the system).  Make the structures
      opaque and the interface more strict.
    - Remove PFIL_HOOKS option by making pfil(9) mandatory.
