Subject: [PATCH net-next 0/3] inet: frags: followup to 'inet-frags-avoid-possible-races-at-netns-dismantle'

Latest patch series ('inet-frags-avoid-possible-races-at-netns-dismantle')
brought another syzbot report shown in the third patch changelog.

While fixing the issue, I had to call inet_frags_fini() later
in IPv6 and ilowpan.

Also I believe a completion is needed to ensure proper dismantle
at module removal.

Eric Dumazet (3):
  inet: frags: uninline fqdir_init()
  inet: frags: call inet_frags_fini() after unregister_pernet_subsys()
  inet: frags: fix use-after-free read in inet_frag_destroy_rcu
