Subject: [PATCH 01/14] block/nbd: BDRVNBDState: drop unused connect_err
Date: Wed, 7 Apr 2021 13:46:24 +0300 [thread overview]
Message-ID: <20210407104637.36033-2-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20210407104637.36033-1-vsementsov@virtuozzo.com>
The field is actually unused. Let's make things a bit simpler dropping
it and corresponding logic.
