Indeed, and thanks, I almost forgot the reason why I introduced it :( This is actually for fprobe_exit_handler() to pass the return address to user handler so that the fprobe-events can show the return address correctly. When I implemented the fprobe-events, I found this was required but splitted from the main fprobe event patch but forgot to update the description.
Let me update it.
Thank you!
