David Wilder 1cbf90985f netfilter: iptables: Split ipt_unregister_table() into pre_exit and exit helpers. ... The pre_exit will un-register the underlying hook and .exit will do the table freeing. The netns core does an unconditional synchronize_rcu after the pre_exit hooks insuring no packets are in flight that have picked up the pointer before completing the un-register.
