I would suggest to pursue the lone kernel patch separately. Hopefully
that can be merged soon, once the remainin problems with that are
addressed.

As a high level comment, can you add support for CSV mode?
(-x, in other tools)

I assume most people would data mine the output in some form,
and that's much easier with a more machine oriented format.

Also you should probably have the standard perf conventions
for output fds (--log-fd, --output, default to stderr). otherwise
the output may often be lost.
