Updating LDD3

Updating LDD3

[Liam Ryan]

I'm currently working through the Linux Device Drivers 3rd edition
(https://lwn.net/Kernel/LDD3/) and much of the code is outdated. 

Right now I'm going through chapter 3 and rewriting the scull.c sample
code so that it will compile with 4.14.x

I'm wondering about the Creative Commons license on the LDD3 book. I believe I would be able to annotate or alter the pdf files and re-publish them once I respect the license, however I'm wondering if this would be considered bad form? I assume there's a reason somebody else has not done this to date?

Obviously as a kernel newbie I'm not best positioned to do this work but
I'm happy to make a start and publish to a wiki or similar in a few
months once I've gone through everything. 

Thanks, 
Liam

I think you can update and re-publish the example code and don't break the original comment lines. 
At least I think this.

Thanks I had found this repo which is a great reference for when I get
stuck in my own attempt to update the old code, however I believe this repo is also outdated. For instance it calls aio_complete on line 405 of main.c of scullc which I found has since been removed ( or I made a huge error :) ). 

Leaving that aside I'm referring to updating the book itself rather than the code as the text makes reference to the code as written in 2005.

I'll ask the question on the debian-legal list as recommended, I think
the threads diverged at some point.

Liam

This is the repo I worked off of

https://github.com/duxing2007/ldd3-examples-3.x

> Leaving that aside I'm referring to updating the book itself rather than the code as the text makes reference to the code as written in 2005.

Isn't that the same thing? You need updated code to update the
book. Not to throw water on your enthusiasm but that book is amazingly
well written, there are [throw away] comments in that book that have
taught me loads about subtle concepts of kernel development.

I would be very hesitant removing any text from that book if one is not
_very_ experienced. There is a wealth of knowledge in it and the few
functions that are out of date do little to reduce it's educational
value IMO.

Sure, it would be nice to have a few of the newer kernel features
included but again this is not a job for just anyone. Those guys that
wrote that book are seriously experienced.

Hope this helps,
Tobin.
