How do I get a linux kernel patch set from the mailing list?

I don’t subscribe to the linux-kernel mailing list, but I want to get a set of patches that were posted a few weeks ago and apply them to my kernel for testing. I’m very familiar with patching, building, etc. My question is, what’s the best way to get a copy of this patch set? It’s not applied to any Git repo that I’m aware of, it’s just been posted to the mailing list for discussion.

Add TCP congestion control variant to Linux Ubuntu

I want to test different variants of TCP in Linux Ubuntu. I have Ubuntu 14.04 LTS with Kernel version 3.14. When I check the available congestion control algorithm using the following command sysctl net.ipv4.tcp_available_congestion_control I get only: cubic and reno. However, I want to test other variants like Hybla, HighSpeed. If I run the menuconfig I can select the variants which I want and compile the Kernel. But in my case, I already have the kernel compiled so is it possible to have some Linux package which contains TCP variants as loadable kernel modules?
