Avi,
Do you consider these tracepoints itself ABI or not?
we are preparing some patches that add trace points in addition to
a: these stats
b: our debug feature
If this is not ABI, then we could work on these trace points step by step,
e.g. first use the existing stat/debug as trace point places, then combine,
add or remove trace points later on if necessary.
