Subject: [PATCH 15/18] drm/amdgpu: use dma-fence annotations for gpu reset code
Date: Thu,  4 Jun 2020 10:12:21 +0200
Message-ID: <20200604081224.863494-16-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20200604081224.863494-1-daniel.vetter@ffwll.ch>

To improve coverage also annotate the gpu reset code itself, since
that's called from other places than drm/scheduler (which is already
annotated). Annotations nests, so this doesn't break anything, and
allows easier testing.
