Hi Thomas,

The only relevant list was linux-kernel@vger.kernel.org

This is the only list which the MAINTAINERS file advises to add. I did 
wonder about a dedicated perf list, as I seem to miss mails also.

Hi Peter, Ingo, Arnaldo,

Should linux-perf-users address be added for perf-related patches? If 
so, should we add it to the maintainers file? If not, why no dedicated list?

Thanks,
John
