You do not even need patches for it. You can do it as well with a TBF filter in the qdisc and a u32 filter that selects RSTs (it is even a standard example in iproute2)
Another way that may work is to set the send buffer of tcp_socket in tcp_ipv4.c to a really small value, so that only one RST packet fits. Then you get a good load limit implicitely in the stack (there should be probably a sysctl for that)
