For what it's worth, this kind of measurement widget could be usefully recast as a pure client of the lttng/systemtap markers that Mathieu is still working on. Instead of the custom pc_start/pc_stop functions, you would have generic markers to identify the start/end spots, and a bit of callback code to compute/export the statistics to procfs. - FChE - 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/
