I'm relatively new to Linux kernel programming. The key problem for me 
was - and still is - that there is so overwhelmingly much information 
available, that it's virtually impossible to find out things that would 
be obvious for long-time developers, like finding out who the maintainer 
for a piece of code is. I still don't know that, by the way. How do I 
find the "CC" list that I'm supposed to send bugs/suggestions/patches to 
for a given piece of code?

I guess that a document on 
would help, but then again finding that particular document - or 
realizing that it even exists (it doesn't, does it?) - would be the next 

It's quite easy to find out how one goes about writing a driver, but the 
process surrounding it - such as finding whether such a driver already 
exists, where to go for technical advice and where to post the git patch 
for inclusion in mainline is something that no one seems to want to 
dwell on.

Sorry if I'm ranting here. Maybe in time I'll learn to behave...
