From dff10e9e637663c8c5dd0bae1a8f0e899cbb4a36 Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Wed, 2 Nov 2011 10:32:14 -0400 Subject: [PATCH] tipc: Minor optimization to rejection of connection-based messages Modifies message rejection logic so that TIPC doesn't attempt to send a FIN message to the rejecting port if it is known in advance that there is no such message because the rejecting port doesn't exist.
