Message-Id: <1442913260-3925-29-git-send-email-pablo@netfilter.org>
Date: Tue, 22 Sep 2015 11:14:18 +0200
From: Pablo Neira Ayuso <pablo@...filter.org>
To: netfilter-devel@...r.kernel.org
Cc: davem@...emloft.net, netdev@...r.kernel.org
Subject: [PATCH 28/30] netfilter: Pass priv instead of nf_hook_ops to netfilter hooks
From: "Eric W. Biederman" <ebiederm@...ssion.com>
Only pass the void *priv parameter out of the nf_hook_ops. That is
all any of the functions are interested now, and by limiting what is
passed it becomes simpler to change implementation details.
