Subject: [PATCH 03/13] fixup! KVM: selftests: Support multiple vCPUs in demand paging test
Date: Fri, 14 Feb 2020 15:59:10 +0100 [thread overview]
Message-ID: <20200214145920.30792-4-drjones@redhat.com> (raw)
In-Reply-To: <20200214145920.30792-1-drjones@redhat.com>
[guest_code() can't return, use GUEST_ASSERT(). Ensure the number
of guests pages is compatible with the host.]
