From f7fb9d20ade55e538efe91477014b6b367ecd802 Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Thu, 26 Apr 2012 17:53:03 -0400 Subject: tipc: Create helper routine to delete unused name sequence structure Replaces two identical chunks of code that delete an unused name sequence structure from TIPC's name table with calls to a new routine that performs this operation. This change is cosmetic and doesn't impact the operation of TIPC.
