True. Perhaps we should do the double underscore trick. Instead of: trace_invoke_foo() use: trace_invoke__foo() Which will make it more visible to what the trace event is. Hmm, we probably should have used: trace__foo() for all tracepoints, as there's still functions that are called trace_foo() that are not tracepoints :-p -- Steve
