Subject: [PATCH 5/5] KVM: x86: Make gtod_is_based_on_tsc() return 'bool'
Date: Tue,  9 Jan 2024 15:11:21 +0100	[thread overview]
Message-ID: <20240109141121.1619463-6-vkuznets@redhat.com> (raw)
In-Reply-To: <20240109141121.1619463-1-vkuznets@redhat.com>

gtod_is_based_on_tsc() is boolean in nature, i.e. it returns '1' for good
clocksources and '0' otherwise. Moreover, its result is used raw by
kvm_get_time_and_clockread()/kvm_get_walltime_and_clockread() which are
'bool'.

No functional change intended.
