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

Hi all,

Today's linux-next merge of the net-next tree got a conflict in
net/netfilter/nf_log.c between commit e71456ae9871 ("netfilter: Remove
checks of seq_printf() return values") from the vfs tree and commit
0c26ed1c07f1 ("netfilter: nf_log: Introduce nft_log_dereference()
macro") from the net-next tree.

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