Would you be open to the idea that sendfile could be extended to
generate error queue completions if the network socket has
SO_ZEROCOPY set?
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.
