:-) I think that when we decide that it is so better to change defaults like we did this time, we should be required to add a big fat warning (a --tui popup, use the first lines on --stdio, etc) about why the default was changed and allow quick, easy opt out, restoring previous behaviour after the user, being warned, knows what to expect, tries it, and then is in a better position to decide if keeping the new default is what is desired. - Arnaldo > > >> Samples: 5K of event 'cycles', Event count (approx.): 2268660922 > > >> Children Self Symbol > > >> + 46.42% 0.04% [k] system_call_fastpath > I'll just turn it off until I figure out what cool stuff this is telling > me. why that symbol becomes the number one hit, and why total% > 100. > To me, it looks like top smoked it's breakfast, went to lala land ;-) Yeah, its confusing, I'll let Namhyung explain it ;-) :-) - Arnaldo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
