Subject: [PATCH v3 3/5] block-copy: move progress_set_remaining in block_copy_task_end
Date: Tue, 8 Jun 2021 09:33:42 +0200 [thread overview]
Message-ID: <20210608073344.53637-4-eesposit@redhat.com> (raw)
In-Reply-To: <20210608073344.53637-1-eesposit@redhat.com>
Moving this function in task_end ensures to update the progress
anyways, even if there is an error.
It also helps in next patch, allowing task_end to have only
one critical section.
