Subject: [PATCH v6 06/18] drm/virtio: remove ttm calls from in virtio_gpu_object_{reserve,unreserve}
Date:   Tue,  2 Jul 2019 16:18:51 +0200
Message-Id: <20190702141903.1131-7-kraxel@redhat.com>
In-Reply-To: <20190702141903.1131-1-kraxel@redhat.com>
References: <20190702141903.1131-1-kraxel@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Call reservation_object_* directly instead
of using ttm_bo_{reserve,unreserve}.

v4: check for EINTR only.
v3: check for EINTR too.
