There is no facility to pass mount flags all the way down to a device driver. This also is not a per mount instance type of feature since several mountable partitions may reside on the same device. CAM currently lacks code to modify mode pages and maintain those modifications across bus reset and BDR events. This could be added, but it would be IMHO lots of complexity for limited gain. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
