[Bug runtime/6964] process probes cause kernel crash on f9

[wcohen at redhat dot com]

Compiled the instrumentation one line 'probe process.end {}' separately into
module then ran with:

staprun -vv 6964f.ko -c ls

This caused a crash right after the following line:

stapio:stp_main_loop:372 detaching pid 30260

Looks like things are going wrong after when the following line from
systemtap/runtime/staprun/mainloop.c is attempted:

          int rc = ptrace (PTRACE_DETACH, target_pid, 0, 0);


Is there a ptrace tests that register utrace engines similar to what systemtap
generates in the instrumentation module?
