The ftracetest script is a fairly complete test framework for tracefs-like subsystem, but it can only be used for ftrace selftests.
If OPT_TEST_DIR is provided and includes a function file, use that as test directory going forward rather than just grabbing tests from it.
Generalise function names like initialize_ftrace to initialize_system.
Add the --rv argument to set up the test for rv, basically changing the trace directory to $TRACING_DIR/rv and displaying an error if that cannot be found.
This prepares for rv selftests inclusion.
