In case anyone is interested, as a followup, the above advice works
perfectly. The code now looks like this:

<code>
static int delete_ct_record( u_int32_t src, u_int16_t sport, u_int32_t
dst, u_int16_t dport)
{
      struct ip_conntrack_tuple tuple;
      struct ip_conntrack_tuple_hash *h;

      memset( &tuple, 0, sizeof( tuple));
      tuple.src.ip = src;
      tuple.src.u.tcp.port = sport;
      tuple.dst.ip = dst;
      tuple.dst.u.tcp.port = dport;
      tuple.dst.protonum = IPPROTO_TCP;
      h = ip_conntrack_find_get( &tuple, NULL);
      if (!h)
              return -ENOENT;
      if (del_timer( &h->ctrack->timeout))
              h->ctrack->timeout.function( (unsigned long)h->ctrack);
      ip_conntrack_put( h->ctrack);
      return 1;
}
</code>

As well, the kill_ct_record() function has been removed as it is now
useless. Thanks for all the help, Patrick especially. :)
