I thought about this and I'd be happy to do it as long as you don't
mind me asking questions about parts I don't understand (which
shouldn't be a problem from my past experience ;-)). I am spending
time understanding the code anyway so I'd rather update the main
documentation than my own notes for the benefit of everyone ;-) As you
said, it'll help familiarization of the code. Btw I got rid of those
extra rcu_state externs too, I'll send that patch out today and
continue working on things next week...

Thanks!
