displays the commit I was referring to, namely, the one containing this

+ timeo = sock_rcvtimeo(sk, flags & MSG_DONTWAIT);
+
+ do {
+ skb = __skb_try_recv_datagram(sk, flags, peeked, off, err,
+ &last);
+ if (skb)
+ return skb;
+
+ if (*err != EAGAIN)
+ break;
+ } while (timeo &&
+ !__skb_wait_for_more_packets(sk, err, &timeo, last));

which added the inverted test, IOW, if this is the wrong hash, I have no
idea what the right one could be. I'll resubmit this with the 'one line
summary' added. After noticing the issue around 23:10 UK time yesterday,
I was in a bit of a hurry and stopped reading the 'Fixes' text in
SubmittingPatches after the "with the first 12 characters".
