[PATCH v3 3/5] KVM: selftests: Move GUEST_ASSERT_EQ to utils header

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
