From 17450351fff8cc63624c0ab4d46a8f5eec37c802 Mon Sep 17 00:00:00 2001 From: Jianfeng Tan Date: Wed, 29 Jun 2016 03:23:03 +0000 Subject: [PATCH] net/virtio-user: fix build on Suse 11 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On some older systems, such as SUSE 11, the compiling error shows as: .../dpdk/drivers/net/virtio/virtio_user/virtio_user_dev.c:67:22: error: ‘O_CLOEXEC’ undeclared (first use in this function) The fix is to use EFD_CLOEXEC, which is defined in sys/eventfd.h, instead of O_CLOEXEC which needs _GNU_SOURCE defined on some old systems.
