From: Weilin Wang Date: Tue, 20 Jun 2023 17:00:26 +0000 (-0700) Subject: perf test: Add skip list for metrics known would fail X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a0f1cc18f91faf75a321135ac08385a4f260a87d;p=linux.git perf test: Add skip list for metrics known would fail Add skip list for metrics known would fail because some of the metrics are very likely to fail due to multiplexing or other errors. So add all of the flaky tests into the skip list.
