Subject: [PATCH] fix inverted test in __skb_recv_datagram
Date: Mon, 07 Dec 2015 23:30:58 +0000 [thread overview]
Message-ID: <87vb8925vx.fsf_-_@doppelsaurus.mobileactivedefense.com> (raw)
In-Reply-To: <874mft7sur.fsf_-_@doppelsaurus.mobileactivedefense.com> (Rainer Weikusat's message of "Mon, 07 Dec 2015 23:15:56 +0000")
As the kernel generally uses negated error numbers, *err needs to be
compared with -EAGAIN (d'oh).
