Subject: [PATCH] KVM: selftests: Tweak time measurement flag in kvm_page_table_test
Date: Mon, 19 Apr 2021 18:49:47 +0800 [thread overview]
Message-ID: <20210419104947.38544-1-wangyanan55@huawei.com> (raw)
Also use CLOCK_MONOTONIC flag to get time in kvm_page_table_test.c,
since that's what all the kvm/selftests do currently. And this will
be consistent with function timespec_elapsed() in test_util.c.
