See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-block@vger.kernel.org SCSI_IOCTL_SEND_COMMAND has been deprecated longer than bsg exists and has been warning for just as long. More importantly it harcodes SCSI CDBs and thus will do the wrong thing on non-scsi bsg nodes.
