Perhaps there are not that many users of callchains because the default is not what they're used to see? Motivation for the change came from a video from Chandler, that resurfaced the callchain default issue, Chandler? Anedoctally, he tweeted about it and people seemed to like it. > > Ingo, what do you think? What about providing a hotkey, in the tui, to toggle caller/callee views, and another hotkey to save that in ~/.perfconfig so that becomes the new default? In the --stdio mode we need to add a warning in the first lines, something like: # This is caller (or callee) based, please use --callchain ... to change it One way or the other people will disagree, so making it easy to switch to the preferred way would be nice to have? - 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/
