Subject: linux-next: manual merge of the net-next tree with the net tree

Hi all,

Today's linux-next merge of the net-next tree got a conflict in
net/ipv4/inet_diag.c between commit c8e2c80d7ec0 ("inet_diag: fix
possible overflow in inet_diag_dump_one_icsk()") from the net tree and
commit a4458343ac59 ("inet_diag: factorize code in new
inet_diag_msg_common_fill() helper") from the net-next tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
