| Subject: tcp: clear tp->data_segs{in|out} in tcp_disconnect() |
| |
| From: Eric Dumazet <edumazet@google.com> |
| |
| [ Upstream commit db7ffee6f3eb3683cdcaeddecc0a630a14546fe3 ] |
| |
| tp->data_segs_in and tp->data_segs_out need to be cleared |
| in tcp_disconnect(). |
| |
| tcp_disconnect() is rarely used, but it is worth fixing it. |
| |
| Fixes: a44d6eacdaf5 ("tcp: Add RFC4898 tcpEStatsPerfDataSegsOut/In") |
