From 3f2650377631aed3bc26fdbc3a2eef6e33cdf7e7 Mon Sep 17 00:00:00 2001 From: Tom Gundersen Date: Sat, 5 Jul 2014 14:53:54 +0200 Subject: networkd: netdev - rename 'enslave' to 'join' Enslave only really makes sense when referring to bridges and bonds, so try to be a bit more neutral. --- src/network/networkd-link.c | 40 +++++++++++++++---------------- src/network/networkd-netdev.c | 56 +++++++++++++++++++++++++++---------------- src/network/networkd.h | 10 ++++---- 3 files changed, 60 insertions(+), 46 deletions(-) (limited to 'src') diff --git a/src/network/networkd-link.c b/src/network/networkd-link.c index 9e057ce0ff..ccf818115b 100644 --- a/src/network/networkd-link.c +++ b/src/network/networkd-link.c @@ -1732,14 +1732,14 @@ static int link_up(Link *link) { return 0;
