From d01c18ff821b81baa3b99329ebf051c6a1bfd4ee Mon Sep 17 00:00:00 2001 From: Ferruh Yigit Date: Tue, 22 Jan 2019 15:44:28 +0000 Subject: [PATCH] kni: fix build for dev_open in Linux 5.0 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Build error seen with Linux kernel 5.0 and when CONFIG_RTE_KNI_KMOD_ETHTOOL is enabled. build error: .../build/build/kernel/linux/kni/ixgbe_ethtool.c:1746:4: error: too few arguments to function ‘dev_open’ dev_open(netdev); ^~~~~~~~ In file included from .../build/kernel/linux/kni/ixgbe_ethtool.c:18: .../linux/linux/include/linux/netdevice.h:2620:5: note: declared here int dev_open(struct net_device *dev, struct netlink_ext_ack *extack); ^~~~~~~~ .../build/build/kernel/linux/kni/igb_ethtool.c:1812:4: error: too few arguments to function ‘dev_open’ dev_open(netdev); ^~~~~~~~ In file included from .../build/build/kernel/linux/kni/igb_ethtool.c:15: .../linux/linux/include/linux/netdevice.h:2620:5: note: declared here int dev_open(struct net_device *dev, struct netlink_ext_ack *extack); ^~~~~~~~ dev_open() is changed in Linux kernel version 5.0 and now requires a new parameter, 'struct netlink_ext_ack *extack'.
