Actually, try to understand the organization of the Linux kernel as a
newbie. The way pointers are used often makes it very difficult to tie
things together. You end up using nested series' of greps and it gets to be
more than a little difficult, conceptually.

I haven't seen much useful documentation of kernel structure, just bits and
pieces. Without that, C code heavy in pointer use isn't any easier to
understand than class-rich C++ code....
