NAME
       ata_scsi_queuecmd - Issue SCSI cdb to libata-managed device

SYNOPSIS
       int ata_scsi_queuecmd(struct Scsi_Host * shost, struct scsi_cmnd * cmd);

ARGUMENTS
       shost
	   SCSI host of command to be sent

       cmd
	   SCSI command to be sent

DESCRIPTION
       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.

LOCKING
       ATA host lock

RETURNS
       Return value from __ata_scsi_queuecmd if cmd can be queued, 0 otherwise.
