Olaf Kirch 93fbf1a5de [PATCH] Keep nfsd from exiting when seeing recv() errors 
I submitted this one previously - svc_tcp_recvfrom currently returns
any errors to the caller, including ECONNRESET and the like.

This is something svc_recv isn't able to deal with:

	len = svsk->sk_recvfrom(rqstp);
	[...]
	if (len == 0 || len == -EAGAIN) {
		[...]
		return -EAGAIN;
	}

	[...]
	return len;

The nfsd main loop will exit when it sees an error code other than
EAGAIN.

The following patch fixes this problem

svc_recv is not equipped to deal with error codes other than EAGAIN,
and will propagate anything else (such as ECONNRESET) up to nfsd,
causing it to exit.
