-        but I always wanted to read it, and this was the only way. I
-        simply explain some best practices, and give reading entry-points
-        into the kernel sources. I avoid implementation details: that's
-        what the code is for, and I ignore whole tracts of useful
-        routines. This document assumes familiarity with C, and an
-        understanding of what the kernel is, and how it is used. It was
-        originally written for the 2.3 kernels, but nearly all of it
