Subject: [PATCH 4/7] drm/amdgpu: fix using shared fence for exported BOs
Date: Mon, 24 Sep 2018 13:58:16 +0200 [thread overview]
Message-ID: <20180924115819.2116-5-christian.koenig@amd.com> (raw)
In-Reply-To: <20180924115819.2116-1-christian.koenig-5C7GfCeVMHo@public.gmane.org>
It is perfectly possible that the BO list is created before the BO is
exported. While at it cleanup setting shared to one instead of true.
