What is the good starting point to understand linux kernel? I know you
are going to say Understanding the Linux Kernel, but that is for 2005!
and kernel 2.6.
We know that currently, the latest version is 4.4 and the version
number updates quickly. So, where can I find the core of IO
architecture, page cache, block layer and ... for the most stable
architecture and not the version number?
Regards,
Mahmood

The best book you might find is Professional Linux Kernel architecture [1]
Other than that, read the source code!
thanks,
Daniel.

Man, it's huge and linux has evolved into a giant jump table these
days. I started programming on it in the 2.2 days and it was fairly
sophisticated them. You could start
with reviewing what's in the /kernel directory. For I/O study the bio
architecture. FOr block layer start in drivers/block.
Your best bet is to clone it, get yourself a good kernel debugger to
step through code and explore how things work.
start by cloning it so you have your own copy. Download and install
git then clone Linus' tree.
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
Then you can also get the linux-stable tree which has all the stable
versions of Linux
git clone https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
if you need a good kernel debugger, try this one

If you have questions post them here. They may get lost in the noise
but if I'm around I'll try to help you. I know linux fairly well, but
it changes a lot and I do know the areas you asked about and can help
you.
Have fun. Don't get put off by folks seeming to ignore you, people are
just very busy and most of them totally immersed in fixing their own
areas but there are a few of us who will respond to you.
Jeff

OK thank you very much. I read the Oreily's book but I thought some
of the functions may have changed in recent versions. So, instead of
greping to see what is what, I asked the question to become sure.
Thanks again.

Mahmood
