Subject: [PATCH] xen/balloon: add header guard
Date: Tue, 28 Jul 2020 13:42:35 +0200 [thread overview]
Message-ID: <20200728114235.58619-1-roger.pau@citrix.com> (raw)
In-Reply-To: <20200727091342.52325-5-roger.pau@citrix.com>
In order to protect against the header being included multiple times
on the same compilation unit.

This is required as a pre-patch to use ZONE_DEVICE, or else the
fallback of including the balloon header might not work properly.
