Subject: [PATCH 4.4 03/34] inet: frags: refactor ipfrag_init()

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eric Dumazet <edumazet@...gle.com>

commit 483a6e4fa055123142d8956866fe2aa9c98d546d upstream.

We need to call inet_frags_init() before register_pernet_subsys(),
as a prereq for following patch ("inet: frags: use rhashtables for reassembly units")
