Interesting question, makes me do a bit research by reading the documentation. If you check kprobes.txt in Documentation folder of kernel source tree, in section 1.3.1 you'll read: "While the probed function is executing, its return address is stored in an object of type kretprobe_instance." I guess, you should check the return address in that object. -- regards, Mulyadi Santosa Freelance Linux trainer blog: the-hydra.blogspot.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecar...@nl.linux.org Please read the FAQ at http://kernelnewbies.org/FAQ
