Subject: [PATCH 20/25] netfilter: nf_tables: pass context to nf_tables_updtable()
Date: Wed, 21 May 2014 11:43:17 +0200	[thread overview]
Message-ID: <1400665402-5835-20-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1400665402-5835-1-git-send-email-pablo@netfilter.org>

So nf_tables_uptable() only takes one single parameter.
