From 73cf0e923d685a6a1b7754c7d29cc14944f271d9 Mon Sep 17 00:00:00 2001 From: zhuyj Date: Wed, 26 Nov 2014 10:25:58 +0800 Subject: [PATCH] ipv6: Remove unnecessary test The "init_net" test in function addrconf_exit_net is introduced in commit 44a6bd29 [Create ipv6 devconf-s for namespaces] to avoid freeing init_net. In commit c900a800 [ipv6: fix bad free of addrconf_init_net], function addrconf_init_net will allocate memory for every net regardless of init_net. In this case, it is unnecessary to make "init_net" test. CC: Hong Zhiguo CC: Octavian Purdila CC: Pavel Emelyanov CC: Cong Wang Suggested-by: David S.
