Subject: [PATCH 2/3] KVM: SVM: Move svm_complete_interrupts() into svm_vcpu_run()
Date: Wed,  9 Sep 2020 10:55:19 +0800	[thread overview]
Message-ID: <1599620119-12971-1-git-send-email-wanpengli@tencent.com> (raw)

From: Wanpeng Li <wanpengli@tencent.com>

Moving svm_complete_interrupts() into svm_vcpu_run() which can align VMX 
and SVM with respect to completing interrupts.
