Note, I just posted an RFC stable event patch set. I would like any tool
that does general analysis, to use stable events and not random raw
events created by the perspective maintainers.
The tool could tap into the raw events, but I don't like the "trace
check" I think anything that the trace needs should be guaranteed there
(with the stable tracepoints).
The tracepoints used for general analysis should be stable, anything
else is just shear bonus.
