I just came back from my trip with over 300 patches to review :-p Luckily, for me, Masami is now a co-maintainer and has started that process already :-) When I catch up, I'll take a look at this more closely, and we (Guenter and I) will be running with DEBUG_OBJECTS enabled which will hopefully help catch missed places. At least for the drivers we care about ;-) -- Steve
