Issue scsi cdb to libata-managed device
int ata_scsi_queuecmd(struct Scsi_Host * shost, struct scsi_cmnd * cmd);
shost
SCSI host of command to be sent
cmd
SCSI command to be sent
In some cases, this function translates SCSI commands into ATA taskfiles, and queues the taskfiles to be sent to hardware. In other cases, this function simulates a SCSI device by evaluating and responding to certain SCSI commands. This creates the overall effect of ATA and ATAPI devices appearing as SCSI devices.
ATA host lock
Return value from __ata_scsi_queuecmd if cmd can be queued, 0 otherwise.
