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. -- Steve
