If you are a beginner it might be convenient to look on a small 
subsystem first. The filesystem is really big and complicated, I think.
If you are familiar with the embedded world, maybe something like spi or 
i2c might be a good starting point.

If you want to understand networking, maybe starting with the tun/tap 
kernel module and try to understand how it "injects"/"grabs" 
packets/frames from/to userspace. This way you learn something on the 
data structures of the network subsystem.

Just my 3 cents.
Cheers,
Matthias
