BTW, I'm considering to add an option to allow putting kprobes on notrace function - just for debugging ftrace by kprobes. That is "developer only" option so generally it should be disabled, but for debugging the ftrace, we still need it. Or should I introduce another kprobes module for debugging it?
Thank you,
