Subject: [PATCH] KVM: x86: avoid clearing pending exception event twice
Date: Sat, 18 Jan 2020 10:41:55 +0800 [thread overview]
Message-ID: <1579315315-6444-1-git-send-email-linmiaohe@huawei.com> (raw)
From: Miaohe Lin <linmiaohe@huawei.com>
The exception pending event is cleared by kvm_clear_exception_queue(). We
shouldn't clear it again.
