Subject: [PATCH] conntrack: fix sysctl memory leak
Date: Thu, 10 Mar 2011 10:14:22 -0800	[thread overview]
Message-ID: <20110310101422.62006620@nehalam> (raw)

Message in log because sysctl table was not empty at netns exit
 WARNING: at net/sysctl_net.c:84 sysctl_net_exit+0x2a/0x2c()

Instrumenting showed that the nf_conntrack_timestamp was the entry
that was being created but not cleared.
