Subject: [PATCH v2 03/19] tools/xenstore: preserve errno across corrupt()
Date: Tue, 13 Dec 2022 17:00:29 +0100	[thread overview]
Message-ID: <20221213160045.28170-4-jgross@suse.com> (raw)
In-Reply-To: <20221213160045.28170-1-jgross@suse.com>

Let corrupt() preserve errno in order to be able to simplify error
handling in future.

This is rather easy as the errno value when entering corrupt() is
saved already.
