Subject: [PATCH v3 15/21] parallels: Reverse a conditional in parallels_check_leak() to reduce indents
Date: Fri, 27 Oct 2023 09:46:30 +0200 [thread overview]
Message-ID: <20231027074636.430139-16-alexander.ivanov@virtuozzo.com> (raw)
In-Reply-To: <20231027074636.430139-1-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.
