Subject: [PATCH v6 06/14] block/mirror: drop extra error propagation in commit_active_start()
Date: Sun, 17 Jan 2021 00:52:01 +0300	[thread overview]
Message-ID: <20210116215209.823266-7-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20210116215209.823266-1-vsementsov@virtuozzo.com>

Let's check return value of mirror_start_job to check for failure
instead of local_err.

Rename ret to job, as ret is usually integer variable.
