From 3086523149ef4c15f5e75bb2ed9f43a8f3f95015 Mon Sep 17 00:00:00 2001 From: Parthasarathy Bhuvaragan Date: Tue, 2 Feb 2016 10:52:09 +0100 Subject: [PATCH] tipc: remove filter and timeout elements from struct tipc_subscription Until now, struct tipc_subscription has duplicate timeout and filter attributes present: 1. directly as members of struct tipc_subscription 2. in struct tipc_subscr, which is contained in struct tipc_event In this commit, we remove the references to these elements as members of struct tipc_subscription and replace them with elements from struct tipc_subscr.
