Reading the kernel code is the best way. For reference you can use LDD3
and books from OReilly.

Yes. Its a good book.

Even if the books are older they can give you the general idea about the
thoughts put into the particular subsystem.

If you are a beginner it might be convenient to look on a small 
subsystem first. The filesystem is really big and complicated, I think.
If you are familiar with the embedded world, maybe something like spi or 
i2c might be a good starting point.

If you want to understand networking, maybe starting with the tun/tap 
kernel module and try to understand how it "injects"/"grabs" 
packets/frames from/to userspace. This way you learn something on the 
data structures of the network subsystem.

Just my 3 cents.
Cheers,
Matthias

There is no fast way to learn Filesystem and Networking subsystems,
probably one of the biggest subsystems in kernel.
you should start learning basics from the classic Kernel books and learn
your way around by digging the code.

Hi,

First you need to start with basic of kernel and book for kernel by Robert
Love will help you.Both file-system and networking are major subsystem in
Kernel and required an knowledge of file-system & networking.

Thanks
Sanjeev Sharma

ever used UML (User Mode Linux)? Combine it with gdb and put
breakpoints at the codes you wanna learn...and watch them live
working...

But still, it takes time...so, basically, you need a lot of time....
