NAME
ata_scsi_queuecmd - Issue SCSI cdb to libata-managed device
SYNOPSIS
int ata_scsi_queuecmd(struct scsi_cmnd * cmd, void (*done) (struct scsi_cmnd *));
ARGUMENTS
cmd
SCSI command to be sent
done
Completion function, called when command is complete
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
Releases scsi-layer-held lock, and obtains host lock.
RETURNS
Return value from __ata_scsi_queuecmd if cmd can be queued, 0 otherwise.
