Subject: [kvm-unit-tests PATCH v2 1/8] arm64: microbench: get correct ipi received num
Date: Thu, 2 Jul 2020 11:01:25 +0800	[thread overview]
Message-ID: <20200702030132.20252-2-wangjingyi11@huawei.com> (raw)
In-Reply-To: <20200702030132.20252-1-wangjingyi11@huawei.com>

If ipi_exec() fails because of timeout, we shouldn't increase
the number of ipi received.
