Hey guys,

Pasi mentioned on Li's (and Owen's) patches which provide TRIM/UNMAP support
to the Linux backend/frontend that:
  "
  Isn't the generic name for this functionality "discard" in Linux?

  and "trim" being the ATA specific discard-implementation,
  and "scsi unmap" the SAS/SCSI specific discard-implementation?

  Just wondering..
  "

and it sounds right to me. The problem is of course that the 'feature-trim'
is already in the interface - but I was wondering how much it is set
in stone? Could it be feasible to modify the backend/frontend in Citrix
product to use 'feature-discard' instead? And naturally also the Novell
drivers.
