From: Thierry Reding treding@nvidia.com
The header comment in include/trace/define_trace.h specifies that the TRACE_INCLUDE_PATH needs to be relative to the define_trace.h header rather than the trace file including it. Most instances get that wrong and work around it by adding the $(src) directory to the include path.
While this works, it is preferable to refer to the correct path to the trace file in the first place and avoid any workaround.
