From: "Steven Rostedt (Red Hat)" Created the file tools/testing/ftrace/test.d/functions that will hold helper functions. Current helper functions include: Add clear_trace() helper to reset the trace file Used as a descriptive name to show that "echo > trace" is clearing the trace file. Add disable/enable_tracing() helper calls Add calls that disable and enable tracing respectively by echoing 0 or 1 into tracing_on. Add helper reset_tracer() function Add a helper function reset_tracer() that will clear the current_tracer (echo nop > current_tracer).
