Subject: [PULL 06/34] block/nbd: connect_thread_func(): do qio_channel_set_delay(false)
Date: Tue, 15 Jun 2021 15:47:28 -0500 [thread overview]
Message-ID: <20210615204756.281505-7-eblake@redhat.com> (raw)
In-Reply-To: <20210615204756.281505-1-eblake@redhat.com>
From: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>
nbd_open() does it (through nbd_establish_connection()).
Actually we lost that call on reconnect path in 1dc4718d849e1a1fe
"block/nbd: use non-blocking connect: fix vm hang on connect()"
when we have introduced reconnect thread.
Fixes: 1dc4718d849e1a1fe665ce5241ed79048cfa2cfc
