Re: [PATCH net v2 2/3] net: devmem: return EMSGSIZE on type mismatch

When a devmem payload mixes with a standard page payload, return
-EMSGSIZE instead of -EFAULT. This enables tcp_sendmsg to seamlessly
fall back to creating a new segment instead of failing the socket send.

Sure but AFAIU this was discovered during a ML discussion,
so the change is an improvement for net-next rather than a fix.
Do you have any reason to believe that real applications hit
the error?
