Subject: [Xen-devel] [PATCH v6 01/12] xen: allow only sizeof(bool) variables for boolean_param()
Date: Wed, 26 Feb 2020 13:46:54 +0100 [thread overview]
Message-ID: <20200226124705.29212-2-jgross@suse.com> (raw)
In-Reply-To: <20200226124705.29212-1-jgross@suse.com>
Support of other variable sizes than that of normal bool ones for
boolean_parameter() don't make sense, so catch any other sized
variables at build time.
Fix the one parameter using a plain int instead of bool.
