Subject: [PATCH 45/47] perf tests: Add tests of new pinned modifier
Date: Wed, 7 Aug 2013 18:11:12 -0300 [thread overview]
Message-ID: <1375909874-22073-46-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1375909874-22073-1-git-send-email-acme@infradead.org>
From: Michael Ellerman <michael@ellerman.id.au>
Add a negative test to test__checkevent_pmu_events() to get lots of
coverage of the negative case, ie. when the modifier is not specified.
Add a test of a single event, and of the group case.
