Indeed. > If correct: what is their reason for preferring it over kprobes? > [...] It's not a preference - it's more of a supplement. It's helpful when some combination of such factors exists: - kprobe int3-fault dispatching overhead orders of magnitude too high - fault dispatching not permissible in some areas - local context variables not easily retrievable via dwarf information - dwarf information not available at all - costs of permanently placed but passive marker acceptable >From systemtap's point of view, instrumentation hooked to markers, kprobes, and other facilities like timers, coexist just fine. A greater number of probe-able event sources makes for a richer tool. - 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/
