I thought I was quite clear on my view of SO_ZEROCOPY and its error queue usage, I guess I was not. No I don't think this is a good path at all, when the whole issue is that pretending to handle two different types of completions via two different interfaces is pretty dumb and inefficient to begin with, particularly when we have a method of doing exactly that where the reuse notifications arrive in the normal completion stream. -- Jens Axboe
