Reinette,

Thanks for catching this. I can send v3 of this patch right away (just fixing fir tree order only
needs a compile test, not extensive regression tests).

What are "all the other pending resctrl" fixes?  Since the SNC series is invasive to so many
files & functions, I'll need to re-base SNC on top of everything else that's happening this
cycle.
