Subject[PATCH 45/47] perf tests: Add tests of new pinned modifier
Date
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.
