Note, As I just finished the last of my "tinkering" jobs, I'm now
starting on my bigger projects. The first being the rewrite of the
ftrace function tracing internals.
I'll start it today, but as I have off tomorrow, and my wife has already
filled all my time up with Honeydew tasks (and this extends into the
weekend), I'll have to continue it next week. But hopefully, if all goes
well, I should have an RFC ready by the end of next week.
