Anyone tried to upgrade to btrfs-progs v4.9.1 (Jan 2017) or other btrfs-props?

Thx @Flyer

I really appreciate your work and contribution in order to get those improvements soon into the next releases of Rockstor .
@suman indicated in the following post that a new kernel/btrfs will most likely not show up before 3.9.1

Let us hope things progress well in order to see soon newer versions :smile:
