This happens for the CHILD socket, not the listening one.

Yes, and for listening sockets this is the callback made when a new connection comes in. See net/sunrpc/svcsock.c function svc_tcp_listen_data_ready(), it's doing what you want to do. Make sure to check in a recent kernel because this used to make the same mistake you are making, using state_change instead of data_ready on a listening socket.
