Subject: [kvm-unit-tests PATCH v3 09/10] arm64: microbench: Add test->post() to further process test results
Date: Fri, 31 Jul 2020 15:42:43 +0800
Message-ID: <20200731074244.20432-10-wangjingyi11@huawei.com> (raw)
In-Reply-To: <20200731074244.20432-1-wangjingyi11@huawei.com>
Under certain circumstances, we need to further process microbench
test results, so we add test->post() in the microbench framework,
later patch will use that.
