Well, we don't know. I would imagine though he is not asking for damages, he is asking for a contract to use his code which in turn means that they can use the rest of linux. If you are using his code (especially indirectly), and someone says you can't do this because I will sue you unless you pay me, then you end up paying.
It doesn't matter how much the code is. Remember, at one point in the Java wars, they were talking about 11 lines of code, and claiming billions.
