That's correct. What was the failure mode? We could at least emit a
helpful
message.
I have no log of the error but if my memory is correct it was something
like a missing
plockstat$PID:::rwlock probe. ( For $PID insert the numerical pid of the
process you want to
probe).
It fails like this:
$ plockstat -p 1747
plockstat: failed to compile program: probe description
plockstat1747:::rw-block does not match any probes
