From c6fda282294da882f8d8cc4c513940277dd380f5 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 17 Oct 2007 19:46:47 -0700 Subject: [INET]: Consolidate xxx_frag_create() This one uses the xxx_frag_intern() and xxx_frag_alloc() routines, which are already consolidated, so remove them from protocol code (as promised). The ->constructor callback is used to init the rest of the frag queue and it is the same for netfilter and ipv6. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
