Message-Id: <20110312.152650.246532980.davem@davemloft.net>
Date: Sat, 12 Mar 2011 15:26:50 -0800 (PST)
From: David Miller <davem@...emloft.net>
To: netdev@...r.kernel.org
Subject: [PATCH 8/25] net: Break struct flowi out into AF specific
instances.
Now we have struct flowi4, flowi6, and flowidn for each address
family. And struct flowi is just a union of them all.
It might have been troublesome to convert flow_cache_uli_match() but
as it turns out this function is completely unused and therefore can
be simply removed.
