Would a patch adding dtrace/systemtap-compatible source probes be looked upon favourably?
Yes.
I'm fiddling with the debuginfo-based stap stuff to try and get a histogram of our ntlm_auth timings, but it strikes me that the source-based stuff could be very useful indeed; in particular appropriate DTRACE_PROBEx statements could let us time individual requests from receive to reply, with minimal performance overhead.
That would be great. I previously had patches to do this without dtrace, but the patches were a bit invasive, and they had performance impact. Alan DeKok.
