Subject: [PATCH v4 4/6] KVM: selftests: Move GUEST_ASSERT_EQ to utils header
Date: Thu, 10 Jun 2021 18:10:18 -0700	[thread overview]
Message-ID: <20210611011020.3420067-5-ricarkol@google.com> (raw)
In-Reply-To: <20210611011020.3420067-1-ricarkol@google.com>

Move GUEST_ASSERT_EQ to a common header, kvm_util.h, for other
architectures and tests to use. Also modify __GUEST_ASSERT so it can be
reused to implement GUEST_ASSERT_EQ.
