I'm also going to be touching some of this code too, as I'm waiting for Peter's code to settle down. What are you touching? I'm going to be working on making the dyn_ftrace records smaller, and this is going to change the way the iterations work on modifying the code. This is what I discussed on stage at Kernel Recipes with Willy Tarreau. -- Steve
