Date:	Wed, 01 Feb 2012 16:15:02 -0500 (EST)
From:	David Miller <davem@...emloft.net>
To:	netdev@...r.kernel.org
Subject: [PATCH] ipv6: Remove never used function inet6_ac_check().


It went from unused, to commented out, and never changing after
that.

Just get rid of it, if someone wants it they can unearth it from
the history.

Signed-off-by: David S. Miller <davem@...emloft.net>

Commited to net-next.
