| Subject: tcp: clear tp->total_retrans in tcp_disconnect() |
| |
| commit c13c48c00a6bc1febc73902505bdec0967bd7095 upstream. |
| |
| total_retrans needs to be cleared in tcp_disconnect(). |
| |
| tcp_disconnect() is rarely used, but it is worth fixing it. |
| |
| Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") |
