scsi_ioctl — Dispatch ioctl to scsi device
int scsi_ioctl ( | struct scsi_device * sdev, |
| int cmd, | |
void __user * arg); |
struct scsi_device * sdevscsi device receiving ioctl
int cmdwhich ioctl is it
void __user * argdata associated with ioctl
The scsi_ioctl function differs from most ioctls in that it
does not take a major/minor number as the dev field. Rather, it takes
a pointer to a struct scsi_device.
