In general, with my target vendor hat on, I'd be very interested in
what special SCSI commands the Linux initiator stack might want
to use.  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)
