Subject[PATCH 5.4 016/309] tcp: clear tp->data_segs{in|out} in tcp_disconnect()
Date
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")
