Yeah, I also have some reservations about adding more globals (the trace_event stuff just to associate a plugins list with pevent, probably pevent should have that list, haven't looked 100% at the code), but in general probably this patchset is OK, I think we should take it in and then address those other problems in a followup patchset, d'accord? - 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/
