Which kernel is the most readable one? (lobste.rs)

Today, I realized that I don’t understand how the write syscall works. While I have a good grasp on the OS-Application interface, I have a very fuzzy understanding of OS-hardware interface. What would be the best way to learn that? My first idea is to open the Linux kernel and read that, but Linux does so many things that it might be hard to identify the fraction of the code I am really interested in. Are there better kernels for learning purposes?
