I'll do some updates for it if nobody else wants to.

I think what is easy and what not is relative, if you
are more documented about kernel and use english as
your primary language, many question appear to you as
basic.

I think my question appear to you easy. I know your
answer after you make it. That is because the question
is not all specific it should be. But i think the
answers i get should be more completes. Example:

your response:

ac = alan cox

expected response:

ac is Alan Cox and this patches are oriented to
support x hardware..., (i don't found it in the faq,
may be because alan cox patches only solve problems
aleatory, without one specific purpose, and that is
the only answer i can get to my question), and the
documentation for alan cox patches are in that url
.... that link should be usefull too

sorry but i think the faq is incomplete, i think
useless for what i need too. It have incomplete
answers  and not links references for many important
questions. May be should exist one list or forum
dedicated to: Kernel, Kernel Patches, Kernel Modules,
Kernel Drives and other about Kernel Development and
Bugs Report.

If one question is easy to answer it not make it not
important, is important for who make it, not for you.
If exist other list, forum, ... more related to kernel
 and kernel patched and it's drivers compilation
problems please let me know it.

If i make more questions in that list, i will make
more specific questions in order to get more usefull
answers. But probably not because i think that list is
only for who develop the kernel and not for who
compile and use them and it's patches and drivers.

Thanks for your help and Good luck!!

The LKML FAQ hasn't been updated since:
"Last updated on 21 Nov 2002 by Richard Gooch.
This document is GPL'ed by its various contributors."

and Richard hasn't been heard from lately AFAIK.

I would have just guessed that the FAQ needs some updates...
Doesn't someone out there want a job?

I've been meaning to give the FAQ a thorough going over for a while now.  
(Bits of it are a lot more stale than 2002.)

I sent Richard a FAQ patch a month ago, which he hasn't responded to, but he 
claims to still be active:

I sent him the patch in question on July 17th, but haven't heard anything 
back.  (I've been a bit out of touch in the past month myself getting back 
into grad school, buying a condo, moving, etc, and haven't followed up yet.)

If Richard doesn't have time to do it anymore, and there are patches backing 
up, I could give it a whack.  I'm not exactly dripping with free time myself 
at the moment, but I usually catch up with all the important pending things 
at least once a week.  However, I don't want to usurp anybody's 
maintainership.  (I was planning on possibly making my own tree and then 
feeding him incremental patches at whatever rate he responds...)

Re: patches question

[Rob Landley]

Speaking of which, here's the FAQ update patch I sent Richard last month, just 
in case anybody else finds it useful...

--------------------

Well, here it is.  I ended up completely redoing the section, sorting the data 
into some kind of order, marking deprecated links (stuff referring to 2.0, 
etc) and moving them to the end, grouping similar entries, adding new ones, 
and updating an awful lot of stale links that have moved since the FAQ was 
last updated.

I could try giving you a more gradual series of changes, but I'm about to hit 
the road for a while so I thought I'd send what I have.  Let me know if you 
want me to explain/tweak anything, but keep in mind I might not read my email 
for a week at a time...
