Subject: [PATCH v2 0/2] KVM: selftests: access_tracking_perf_test: skip the test when NUMA balancing is active
Date: Mon, 24 Mar 2025 21:57:39 -0400	[thread overview]
Message-ID: <20250325015741.2478906-1-mlevitsk@redhat.com> (raw)

Due to several issues which are unlikely to be fixed in the near future,
the access_tracking_perf_test sanity check for how many pages are still clean
after an iteration is not reliable when NUMA balancing is active.

This patch series refactors this test to skip this check by default automatically.

V2: adopted Sean's suggestions.

Best regards,
	Maxim Levitsky
