I guess.

I'm uncomfortable with the "outside net/" phrasing of the commit
message. Nothing outside net should used this stuff. Next we'll have
a four letter subsystem abusing it and claiming that it's in a header
so it's a public.

Maybe we should have a conversation about whether io_uring/zcrx.c 
is considered part of networking, whether all patches will get cross
posted and need to get acks from both sides etc. Save ourselves
unpleasant misunderstandings.
