Subject: [Xen-devel] [PATCH v6 04/10] domain: remove the 'is_xenstore' flag
Date: Fri, 16 Aug 2019 18:19:55 +0100 [thread overview]
Message-ID: <20190816172001.3905-5-paul.durrant@citrix.com> (raw)
In-Reply-To: <20190816172001.3905-1-paul.durrant@citrix.com>
This patch introduces a convenience macro, is_xenstore_domain(), which
tests the domain 'options' directly and then uses that in place of
the 'is_xenstore' flag.
