[linux-lvm] Data deduplication for Linux : lessfs

[Mark Ruijter <mruijter gmail com>]

For those who need OpenSource data deduplication today instead of
tomorrow one might take a look at lessfs.
http://www.lessfs.com
I am thinking about starting to work on a data deduplicating
blockdevice, a kernel module called blockless.
For the time being lessfs is now stable and even usable as a blockdevice
with the help of ietd, loop or nbd.
