Subject: [PATCH v3 01/10] KVM: selftests: Rename emulator_error_test to smaller_maxphyaddr_emulation_test
Date: Mon, 31 Oct 2022 11:00:36 -0700 [thread overview]
Message-ID: <20221031180045.3581757-2-dmatlack@google.com> (raw)
In-Reply-To: <20221031180045.3581757-1-dmatlack@google.com>
Rename emulator_error_test to smaller_maxphyaddr_emulation_test and
update the comment at the top of the file to document that this is
explicitly a test to validate that KVM emulates instructions in response
to an EPT violation when emulating a smaller MAXPHYADDR.
