TBH, I haven't done any xenalyze modification, corresponding to this.
However, I'm not really sure it's necessary.
Well, let me put it this way, I run xenalyze on traces collected with
this change, and everything works, and the scheduler-id is shown in the
event. OF course we could improve the situation by decoding it in
xenalyze and showing it explicitly in the trace analysis. I (if this is
what you were referring to) agree it would be nice, but again, it's not
something I've done yet, and not something I can commit on doing in the
next days either. :-(
I don't think it's terrible, as the change only affect traces where the
actual event is also reported encoded, so you have to go check the
headers (or remember stuff) anyway. Again, I completely agree it would
be nice to limit the amount of stuff one has to remember, and I'm up for
it, just not immediately... Is that fine/enough?
Regards,
Dario
