Subject: [PATCH v5 17/22] parallels: Reverse a conditional in parallels_check_leak() to reduce indents
Date: Mon, 11 Mar 2024 19:18:45 +0100 [thread overview]
Message-ID: <20240311181850.73013-18-alexander.ivanov@virtuozzo.com> (raw)
In-Reply-To: <20240311181850.73013-1-alexander.ivanov@virtuozzo.com>
Let the function return a success code if a file size is not bigger than
image_end_offset. Thus we can decrease indents in the next code block.
