From c95477090a2ace6d241c184adc3fbfcab9c61ceb Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 17 Oct 2007 19:48:26 -0700 Subject: [PATCH] [INET]: 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. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
