[kvm-unit-tests PATCH v3 09/10] arm64: microbench: Add test->post() to further process test results

[Jingyi Wang <wangjingyi11@xxxxxxxxxx>]

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.
