Getting to Know the Linux Kernel: A Beginner's Guide (Kelsey Steele & Nischala Yelchuri)
Quick tour of the kernel code organization, how to build the kernel, and the process of sending a patch upstream. The talk is too concise to serve as a guide to someone who is submitting their first patch. If you want a guide, you are better off looking at a tutorial online (the speakers recommend A Beginner’s Guide to Linux Kernel Development)
