But I still did get a 1799 bytes savings between moving the tracepoint out of line but keeping the if, and totally moving the entire functions out of line. Not sure what the discrepancy was there. My last set of numbers came from the default 3.0.0 Debian config, which probably adds more things that call these functions into the kernel proper? But anway, I think this bike shed is complete ;-) > > Acked-by: Ingo Molnar <mingo@...e.hu> Acked-by: Steven Rostedt <rostedt@...dmis.org> -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
