From 277e650ddfc6944ef5f5466fd898b8da7f06cd82 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Mon, 15 Oct 2007 02:37:18 -0700 Subject: [INET]: Consolidate the xxx_frag_kill Since now all the xxx_frag_kill functions now work with the generic inet_frag_queue data type, this can be moved into a common place. The xxx_unlink() code is moved as well. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
