Date: Mon, 10 Apr 2017 18:44:12 -0700 Message-Id: <20170411014414.20280-1-eric@anholt.net> X-Mailer: git-send-email 2.11.0 Sender: linux-arm-msm-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-arm-msm@vger.kernel.org X-Virus-Scanned: ClamAV using ClamSMTP Without this, polling on the dma-buf (and presumably other devices synchronizing against our rendering) would return immediately, even while the BO was busy.
