Both oprofile and readprof are obsolete.

Which list do you use if you want to ask about why a networked app 
schedules too much? lkml or netdev? Both if you want to reach everyone 
who is interested.

Note, perf trace is one out of 9 'perf' sub-commands. I dont think it's 
appropriate to name the list after that one subcommand ...

For your question i'd suggest to Cc: both. It might be relevant to the 
tracing engine, or it might be a perf events or perf tool detail.
