Going to start taking notes about mm again (took some ageees ago in my github before working on the book).
Is useful to keep my own 'war chest' of information that I will otherwise forget.
Beats writing docs (although I have done!) as I can keep these as rough and vague as I like on any topic.
Helps me develop my understanding, as writing always does.
I will eventually give a link for anybody to access this for free but first want to build up knowledge there.
It'll be aimed at myself really only so not going to try to make it comprehensible to anyone not a kernel dev, but I think it'll still contain a ton of useful information.
P.S.. this is EMPHATICALLY not a 2nd book project :P
