Hi Mauro,

If you have any chance to update this series, could you move kprobes.rst under trace/ directly? I think Naveen's idea is better.

Thank you,

There are several files that I was unable to find a proper place for them, and 3 ones that are still in plain old text format.

Let's place those stuff behind the carpet, as we'd like to keep the root directory clean.

We can later discuss and move those into better places.
