Extended copy is one (very complex) case -- and BTW Microsoft seems to plan on using XCOPY LITE with NTFS. Another possibly interesting example would be COMPARE AND WRITE for clustered filesystems. Any other storage operations that FS developers might want from the block device? (Either standard SCSI commands or more speculative stuff that T10 hasn't thought of yet) - R.
