You should indent the above output -- in this specific case, the start marker interferes with git am. Apart from that, I have tested this patch and kretprobe works fine. A minor nit I had is that we end up with a non-dot function in .text without a corresponding function descriptor for kretprobe_trampoline. But, since this is a trampoline, I think that is good.
