From 9776d32537d2bbc251fd1de651e2bb2439474bde Mon Sep 17 00:00:00 2001 From: David Ahern Date: Tue, 27 Mar 2018 18:21:56 -0700 Subject: [PATCH] net: Move call_fib_rule_notifiers up in fib_nl_newrule Move call_fib_rule_notifiers up in fib_nl_newrule to the point right before the rule is inserted into the list. At this point there are no more failure paths within the core rule code, so if the notifier does not fail then the rule will be inserted into the list.
