From 9d561949685749be3d97239eab7d85aa78718108 Mon Sep 17 00:00:00 2001 From: Ying Xue Date: Mon, 5 May 2014 08:56:13 +0800 Subject: [PATCH] tipc: remove TIPC_NAMES_GONE node flag Since previously what all publications pertaining to the lost node were removed from name table was finished in tasklet context asynchronously, we need to TIPC_NAMES_GONE flag indicating whether the node cleanup work is finished or not. But now as the cleanup work has been finished when node lock is released, the flag becomes meaningless for us.
