Subject: [Qemu-devel] [PATCH v5 1/6] nbd/server: fix trace
Date: Sat,  9 Jun 2018 18:17:53 +0300	[thread overview]
Message-ID: <20180609151758.17343-2-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20180609151758.17343-1-vsementsov@virtuozzo.com>

Return code = 1 doesn't mean that we parsed base:allocation. Use
correct traces in both -parsed and -skipped cases.
