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_set lock.
