Subject: [PATCH RFC V3 5/6] KVM: LAPIC: rename start/cancel_hv_tscdeadline to start/cancel_hv_timer
Date: Thu, 13 Oct 2016 19:34:17 +0800 [thread overview]
Message-ID: <1476358458-3525-6-git-send-email-wanpeng.li@hotmail.com> (raw)
In-Reply-To: <1476358458-3525-1-git-send-email-wanpeng.li@hotmail.com>
From: Wanpeng Li <wanpeng.li@hotmail.com>
Rename start/cancel_hv_tscdeadline to start/cancel_hv_timer since
they will handle both APIC Timer periodic/oneshot mode and tsc-deadline
mode.
