Subject: [PATCH 25/33] netfilter: ipset: Fix hash resizing with comments
Date: Fri, 4 Oct 2013 10:33:10 +0200 [thread overview]
Message-ID: <1380875598-5250-26-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1380875598-5250-1-git-send-email-pablo@netfilter.org>
From: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>
The destroy function must take into account that resizing doesn't
create new extensions so those cannot be destroyed at resize.
