Right, evsel/evlist evolved out of tons of refactoring steps moving stuff out of open coded tools (record, report, top) while trying to make it work for those tools, sometimes this resulted in sub-optimal defaults (or plain bugs) like needing a thread_map and/or a cpu_map to do syswide tracing, need to get that clarified and sorted out. - Arnaldo > See, source libraries are the new great thing for collaborative > development - f*ck "cloud"! > :-D :-) - Arnaldo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
