Yes, > And I don't see why we would need additional parameter for > rp_handler() as well. trace_uprobe should use the same fmt = "(%lx <- %lx)" to teport "entry <- exit" info, like trace_kprobe does. And note that, unlike kprobe, the same function can be mmapped at different address by different (or even the same) tasks. But mostly I just wanted to say that yes, we will also teach trace_uprobe to use the new feature before we ask to merge this code.
