generic deduplication? Josef posted some patches back in Jan: http://www.spinics.net/lists/linux-btrfs/msg07818.html http://www.spinics.net/lists/linux-btrfs/msg07819.html (etc) ... if that's what your looking for. i don't know whats all needed to make it work at this point, ie. if you only need the patch to btrfs-progs or some combination. there could be more recent patches but i don't recall anyone talking about any.
