From 3b4bc4a2bfe80d01ebd4f2b6dcc58986c970ed16 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Tue, 22 Jan 2008 06:11:04 -0800 Subject: [NETNS][FRAGS]: Isolate the secret interval from namespaces. Since we have one hashtable to lookup the fragment, having different secret_interval-s for hash rebuild doesn't make sense, so move this one to inet_frags. The inet_frags_ctl becomes empty after this, so remove it. The appropriate ctl table is kept read-only in namespaces. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
