XFS support for TRIM / blkdev_issue_discard?

[Peter Niemayer]

Update: In a recent forum entry
  ( http://www.ocztechnologyforum.com/forum/showthread.php?t=54379&page=11 )
Mark Lord (the maintainer of the "hdparm" tool) states that according
to his tests the newly added support for discarding sectors works in
the Linux "ext4" filesystem.
(Support in GFS2 and swap filesystems has already been available before).

Isn't that another good reason enable XFS to do that, too? :-)
