From ed4ac4221776a5103faf71a4032ca00178d6e66b Mon Sep 17 00:00:00 2001 From: Eugene Crosser Date: Mon, 30 Mar 2015 15:40:42 +0200 Subject: [PATCH] af_iucv: fix AF_IUCV sendmsg() errno When sending over AF_IUCV socket, errno was incorrectly set to ENOMEM even when other values where appropriate, notably EAGAIN. With this patch, error indicator returned by sock_alloc_send_skb() is passed to the caller, rather than being overwritten with ENOMEM.
