Subject: [PATCH 02/17] netfilter: add namespace support for l4proto
From: Gao feng <gaofeng@...fujitus.com>
-nf_ct_(un)register_sysctl are changed to support net namespace,
use (un)register_net_sysctl_table replaces (un)register_sysctl_paths.
and in nf_ct_unregister_sysctl,kfree table only when users is 0.
-Add the struct net as param of nf_conntrack_l4proto_(un)register.
register or unregister the l4proto only when the net is init_net.
-nf_conntrack_l4proto_register call init_net to initial the pernet
data of l4proto.
-nf_ct_l4proto_net is used to get the pernet data of l4proto.
-use init_net as a param of nf_conntrack_l4proto_(un)register.
