I saw it mentioned around, but it does not seem to be in the kernel yet. Is it planned to be introduced? Is there an ETA? Note that I am not very fond of the new dm-thin which is planned to have a multisnap-equivalent feature, because of the fragmentation it will cause (I suppose a defragmenter is long way to come). Not having fragmentation is the reason for using blockdevices instead of loop mounted files after all isn't it? Thanks for your information Spelic
