A comprehensive rework of the textual contents of the Linux kernel source code, isolating code comments from regular computer code. Code comments are annotations that are not meant to be read or executed by the computer; instead, they're mostly meant for notes to provide guidance for others who read the source code.
In Don't kill lockdep, all code comments in the Linux kernel code are emphasised and laid out in a traditional book layout, whereas the actual source code is reduced to plain lines, freeing the non-technical mind to look for its own meaning and interpretation of what's been written.
