Request for info on device drivers

I'm working with a graduate student here at UCSC on a new kind of
file-caching. He and I are looking into implementing it for the ext2
file system, but I have very little (read: none :) kernel hacking
experience.

Basically, I'm looking for pointers to info on how I can make my own
device in /dev that, when read from, outputs a buffer I'm storing info
to inside the kernel.

I'm taking this idea off of /dev/sndstat, sort of. But since I have no
experience in modifying the kernel, I've found myself lost in a twisty
maze of struct inodes and int devs that are masked for just the lower
byte. *grin*

Can anyone give me either the name of a good book to read on device
drivers and kernel hacking, or a pointer to some good docs on this
kind of stuff on the web?

Learning by reading the kernel source is making my head spin :)

Thanks a lot,

Ben Gertzfield
