Yup, what I am currently doing (by hand, it's rather long), is to run
tbench between LTTng patches application to see where the performance
regressions are.

Some automated build/test infrastructure would be good, e.g. :

quilt pop -a

until patchset fully applied
  quilt push
  build kernel
  install kernel
  run tbench, gather results

This should probably be done with both config=Y and config=N for
tracepoint and lttng-specific options.
