Ok send it. I added checks in userspace to make sure we got valid input from users. This is in the svn code.

In the kernel I would add on to them. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
