From c140e93a0c11ac5a56834ac11ddb0f777307b2c1 Mon Sep 17 00:00:00 2001 From: Aaron Lewis Date: Fri, 7 Apr 2023 16:32:51 -0700 Subject: [PATCH] KVM: selftests: Print detailed info in PMU event filter asserts Provide the actual vs. expected count in the PMU event filter test's asserts instead of relying on pr_info() to provide the context, e.g. so that all information needed to triage a failure is readily available even if the environment in which the test is run captures only the assert itself.
