Subject: [Patch v4 04/13] KVM: selftests: Rename 'msr->available' to 'msr->fault_exepected' in hyperv_features test
Date: Mon, 12 Dec 2022 10:37:11 -0800 [thread overview]
Message-ID: <20221212183720.4062037-5-vipinsh@google.com> (raw)
In-Reply-To: <20221212183720.4062037-1-vipinsh@google.com>
From: Vitaly Kuznetsov <vkuznets@redhat.com>
It may not be clear what 'msr->available' means. The test actually
checks that accessing the particular MSR doesn't cause #GP, rename
the variable accordingly.
While on it, use 'true'/'false' instead of '1'/'0' for 'write'/
'fault_expected' as these are boolean.
