I am not objecting, but I wonder if anyone can shed light on

  what fraction of machines/kernels are in the following categories:
    don't have PFIL_HOOKS because they care about performance
    don't have PFIL_HOOKS and don't care
    dot have PFIL_HOOKS and don't need them
    do have PFIL_HOOKS and do need them

  for a machine which is just forwarding, and doesn't need firewalling
  or anything else, how does having PFIL_HOOKS with no actual hooks
  change performance?
