| |
Otherwise load counting is an average. Without this change duration_time in test_memory_bandwidth will alter its value if an earlier test contains duration_time.
This patch fixes an issue that's introduced in the proposed patch: https://lore.kernel.org/lkml/20211124015226.3317994-1-irogers@google.com/ in perf test "Parse and process metrics".
