Does fixing the current write()/writev() problem have any real impact on how we proceed for the "1 char dev to rule them all" idea? >There is some rational for a very driver specific thing, but EEPROM >and snoop? Seriously? That's the thing, I think these are very driver specific [1]. I'm not dead set that the eprom needs to be its own device, it made sense to me, but if others feel the handling should be back in the hfi1 char device I'm fine with that. As for the snoop stuff, perhaps that would be better in rdmavt?
