From aa70200e001fc4d76552c974c94f65ab26020203 Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Fri, 31 Dec 2010 18:59:21 +0000 Subject: [PATCH] tipc: Eliminate use of user registry by topology service Simplifies TIPC's network topology service so that it no longer registers its ports with the user registry, since the service doesn't take advantage of any of the registry's capabilities.
