tcp: Fix broken repair socket window probe patch
Correct previous bad attempt at allowing sockets to come out of TCP repair without sending window probes. To avoid changing size of the repair variable in struct tcp_sock, this lets the decision for sending probes or not to be made when coming out of repair by introducing two ways to turn it off. v2: * Remove erroneous comment; defines now make behavior clear Fixes: 70b7ff130224 ("tcp: allow user to create repair socket without window probes") Signed-off-by: Stefan Baranoff <sbaranoff@gmail.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Andrei Vagin <avagin@virtuozzo.com> Signed-off-by: David S.
