Subject: [PATCH RESEND] xen_hvc: no reason to write the type key on xenstore
Date: Tue, 12 Aug 2014 10:05:22 +0100 [thread overview]
Message-ID: <alpine.DEB.2.02.1408121003570.2293@kaball.uk.xensource.com> (raw)
The backend type is chosen by the toolstack. Regardless, the frontend
should not care, especially given that it cannot have an effect as the
backend is started before this code is run.
