See http://www.infradead.org/rpr.html Sender: linux-scsi-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-scsi@vger.kernel.org Use the proper modern API to transfer cache ownership for incoherent DMA. This also means we can allocate the memory as DMA_TO_DEVICE instead of bidirectional.
