I2O_SCSI_QUEUECOMMAN(9) Message-based devices I2O_SCSI_QUEUECOMMAN(9) NAME i2o_scsi_queuecommand_lck - queue a SCSI command SYNOPSIS int i2o_scsi_queuecommand_lck(struct scsi_cmnd * SCpnt, void (*done) (struct scsi_cmnd *)); ARGUMENTS SCpnt scsi command pointer done callback for completion DESCRIPTION Issue a scsi command asynchronously. Return 0 on success or 1 if we hit an error (normally message queue congestion). The only minor complication here is that I2O deals with the device addressing so we have to map the bus/dev/lun back to an I2O handle as well as faking absent devices ourself. LOCKS takes the controller lock on error path only COPYRIGHT Kernel Hackers Manual 3.11 November 2013 I2O_SCSI_QUEUECOMMAN(9)[top]
