Nice! Although, I probably wont get to look at this till I get back from Berlin. Please send me a friendly "ping" on the 17th.
I'll still add it to my new "todo" folder. Since, just marking patches in my inbox as todo hasn't been working out for me, I've created a separate folder for ftrace patches.
Thanks!
