My worry is because "cat trace" takes quite a long time just reading the BTF arguments. I'm worried it will just get worse with enums as well. I have trace-cmd reading BTF now (just haven't officially released it) and doing an extract and reading the trace.dat file is much faster than reading the trace file with arguments. I'll need to implement the enum logic too in libtraceevent. -- Steve
