Subject: [PATCH 01/15] drm/i915/selftests: Common live setup/teardown
Date: Wed,  3 Jul 2019 10:17:12 +0100	[thread overview]
Message-ID: <20190703091726.11690-1-chris@chris-wilson.co.uk> (raw)

We frequently, and not frequently enough, remember to flush residual
openations and objects at the end of a live subtest. The purpose is to
cleanup after every subtest, leaving a clean slate for the next subtest,
and perform early detection of leaky state.
