From c72fa872a23f03b2b9c17e88f3b0a8070924e5f1 Mon Sep 17 00:00:00 2001 From: Jon Paul Maloy Date: Thu, 22 Oct 2015 08:51:46 -0400 Subject: tipc: eliminate link's reference to owner node With the recent commit series, we have established a one-way dependency between the link aggregation (struct tipc_node) instances and their pertaining tipc_link instances. This has enabled quite significant code and structure simplifications. In this commit, we eliminate the field 'owner', which points to an instance of struct tipc_node, from struct tipc_link, and replace it with a pointer to struct net, which is the only external reference now needed by a link instance.
