>Description:
In /sys/scsi/scsi_ioctl.c the SCIOCCOMMAND ioctl is ifdef'ed out waiting
to be fixed to use copyin/copyout. Here are the comments from the section.

#ifdef notyet /* XXXX Needs to be redone to use copyin/out! */
	case SCIOCCOMMAND: {
		/*
		 * You won't believe this, but the arg copied in
 		 * from the user space, is on the kernel stack
		 * for this process, so we can't write
		 * to it at interrupt time..
		 * we need to copy it in and out!
		 * Make a static copy using malloc!
		 */

This basically make using the SCSI user passthru impossible. This is just
a friendly reminder to get this implemented soon.
