Kees and Jann,

Thank you very much for your comments and advices. I'm a newbie in the
linux kernel development and this is my first attempt. So, I would prefer
to study all your comments before to reply since a big amount of terms
you expose are unknown to me.

In other words, a late reply to this serie comments is not a lack of
interest. Moreover, I think it would be better that I try to understand and
to implement your ideas before anything else.

My original patch serie is composed of 9 patches, so the 3 lasts are lost.
Kees: Have you removed them for some reason? Can you send them for review?

security/fbfam: Add two new prctls to enable and disable the fbfam feature
https://github.com/johwood/linux/commit/8a36399847213e7eb7b45b853568a53666bd0083

Documentation/security: Add documentation for the fbfam feature
https://github.com/johwood/linux/commit/fb46804541f5c0915f3f48acefbe6dc998815609

MAINTAINERS: Add a new entry for the fbfam feature
https://github.com/johwood/linux/commit/4303bc8935334136c6ef47b5e50b87cd2c472c1f

Is there a problem if I ask for some guidance (replying to this thread)
during the process to do my second patch series?

My goal is to learn as much as possible doing something useful for the
linux kernel.

Thanks a lot,
John Wood
