Until now I had the opinion that it's good to let every tracing headers
to be placed in include/trace/* because they are not useful for anything
else than the tracer itself so that we don't encumber include/linux for
private things.

So that we have both tracepoints/trace_events plus the low-level tracers
headers in include/trace/*

I'm not opposite to this change, but seeing this patch and the recent divide
of kmemtrace headers, I would like to know the opinion of Ingo and Steven
about the strict role of include/trace/*
Is it only for tracepoints-like bits, or oslo intended for every private tracing
purposes?


Thanks.
