The old links didn't point to valid locations.
Replace the old links with the new links and test those changes with a
small script: https://github.com/initBasti/markdown_link_check .
______________________________________________________________
In order to find and replace the links, I used the following commands:
grep -rwohP '.' -e "\(https\:\/\/0xax.gitbooks.io\/\S*\)" > links.txt
(Find all links recursivly in the project directories and print out the
only the matches links)
Within links.txt:
Remove the '(' & ')' => :%s/\(//g and :%s/\)//g
Remove duplicates => :sort u
Test if the links work with:
python3 md_link_check.py --pattern 0xax.gitbook --output-file bad.txt
(https://github.com/initBasti/markdown_link_check)
Create replace commands:
:%s/.*/grep -rl & '.' | xargs sed -i 's#&##g'
Enter replacement URL between the 2nd & 3rd '#'
Execute commands: :w !sh

While reading about initcalls around the web and kernel source code I found
that the information of what happens to __init functions not explicitly set to
any initcall list pretty useful. With this patch such information is added.

This patch handle different typos present in the initcall section of the book.
It also reword some paragraphs in order to get it clearer to the reader.
Some example codes were also added in order to help the reader to understand
smaller concepts, like the way initcalls callbacks are named in the object
file.
