| Subject: [PATCH] netfilter: synproxy: synproxy_cpu_seq_next should increase |
| position index |
| |
| commit bb71f846a0002239f7058c84f1496648ff4a5c20 upstream. |
| |
| If .next function does not change position index, |
| following .show function will repeat output related |
| to current position index. |
