Subject: [PATCH 24/25] netfilter: pass 'nf_hook_ops' instead of 'list_head' to nf_queue()
Date: Tue,  4 Sep 2012 01:54:11 +0200	[thread overview]
Message-ID: <1346716452-3080-25-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1346716452-3080-1-git-send-email-pablo@netfilter.org>

From: Michael Wang <wangyun@linux.vnet.ibm.com>

Since 'list_for_each_continue_rcu' has already been replaced by
'list_for_each_entry_continue_rcu', pass 'list_head' to nf_queue() as a
parameter can not benefit us any more.

This patch will replace 'list_head' with 'nf_hook_ops' as the parameter of
nf_queue() and __nf_queue() to save code.
