From 38622f41956f92a06f5b5e42e50746851110d970 Mon Sep 17 00:00:00 2001 From: Ying Xue Date: Tue, 2 Dec 2014 15:00:25 +0800 Subject: [PATCH] tipc: ensure all name sequences are released when name table is stopped As TIPC subscriber server is terminated before name table, no user depends on subscription list of name sequence when name table is stopped. Therefore, all name sequences stored in name table should be released whatever their subscriptions lists are empty or not, otherwise, memory leak might happen.
