1. NAME▲
i2o_scsi_queuecommand_lck - queue a SCSI command
2. SYNOPSIS ▲
int i2o_scsi_queuecommand_lck(struct scsi_cmnd * SCpnt , void (* done ) (struct scsi_cmnd *));
3. ARGUMENTS ▲
SCpnt
scsi command pointer
done
callback for completion
4. 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.
5. LOCKS ▲
takes the controller lock on error path only
