From 2fa3ee93d13ce723d60a4fc4620ed9126c468901 Mon Sep 17 00:00:00 2001 From: Jonathan Toppins Date: Wed, 8 Jun 2022 14:14:57 -0400 Subject: [PATCH] bonding: cleanup bond_create Setting RLB_NULL_INDEX is not needed as this is done in bond_alb_initialize which is called by bond_open. Also reduce the number of rtnl_unlock calls by just using the standard goto cleanup path.
