And, I _think_, that is pretty well documented in the eBPF tracepoint documentation. The patch I'm submitting is a _sample_ of how one can (with a particular version of the kernel) alter the data reported from, or change the logic around, the tracepoints. Ira, I'm totally with you and would like to see more tracepoints used in our subsystem, but latest shit storm related to changes hfi1 debugfs showed that promises, documentation and agreement to change debugfs in any given time are not worth a dime, once anyone from the crowd throws an "ABI" word.
