Code review comment for lp:~kdub/mir/gbm-ext-v2

I agree with the above nit. It's a count of frames so even to exceed uint32 on a 60Hz display will take 2.2 years. A client would have to remember what it rendered 2.2 years ago. So 32-bits is plenty and we also don't need an explicit bit size. Just make it "unsigned int".
