Are you asking after looking at the latest version of my patch-set? Kprobes is done and ack'd. ftrace needs to be broken into two separate changes (setting x after writing, and using text_poke interfaces), unless Steven ack’s them. The changes introduce some overhead (3x), but I think it is a reasonable slowdown for a debug feature. Can you have a look at the series I’ve sent and let me know which patches to drop? It would be best (for me) if the two series are fully merged.
