Immediately after,\nops_free_list() frees the per-net state while concurrent packets might\nstill be executing nf_log_packet() under rcu_read_lock().\"\n\nClear the pointer via .pre_exit to make sure rcu readers have completed\nbefore pernet storage is free'd.  The change in nf_log_syslog.c is only\ndone for consistency: it doesn't use pernet data.",
