Preparation patchset for in-coming (aimed for 4.6) kernel in-band de-duplication patchset.
New kernel dedup will has 2 different dedup backends and a ioctl interface to enable/disable dedup. The ioctl interface and on-disk format (mostly) is determined, so submit this patchset first before de-duplication first.
