Good point.  I have a change to kernel/audit.c that removes the
usage.    I believe the scsi netlink usage is just plain bogus,
and it wants the netlink port identifier instead.

Would anyone mind if we changed the name of the field in netlink from
pid to portid?  It seems to cause a lot of confusion.  We can't change
the user space fields of course but...

Right now because we can now use current using NETLINK_CREDS in the
kernel is unnecessary.
