Subject[PATCH 4.19 51/89] netfilter: nf_conntrack: ct_cpu_seq_next should increase position index
Date
From: Vasily Averin <vvs@virtuozzo.com>

commit dc15af8e9dbd039ebb06336597d2c491ef46ab74 upstream.

If .next function does not change position index,
following .show function will repeat output related
to current position index.
