From 8f92df6ad49da958d97e171762d0a97a3dc738f1 Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Fri, 31 Dec 2010 18:59:19 +0000 Subject: tipc: Remove prototype code for supporting multiple clusters Eliminates routines, data structures, and files that were intended to allow TIPC to support a network containing multiple clusters. Currently, TIPC supports only networks consisting of a single cluster within a single zone, so this code is unnecessary.
