Message-ID: <4714C59E.50209@openvz.org> Date: Tue, 16 Oct 2007 18:07:26 +0400 From: Pavel Emelyanov <xemul@...nvz.org> To: David Miller <davem@...emloft.net> CC: Linux Netdev List <netdev@...r.kernel.org>, devel@...nvz.org Subject: [PATCH 7/7] Consolidate frag queues freeing Since we now allocate the queues in inet_fragment.c, we can safely free it in the same place. The ->destructor callback thus becomes optional for inet_frags.
