| Subject: [PATCH] netfilter: nf_conntrack: ct_cpu_seq_next should increase |
| position index |
| |
| commit dc15af8e9dbd039ebb06336597d2c491ef46ab74 upstream. |
| |
| If .next function does not change position index, |
| following .show function will repeat output related |
| to current position index. |
