btrfs fi show

[Gene Czarcinski <gene@czarc.net>]

I am on Fedora 20-Beta and we just updated to btrfs-progs 
0.20.rc1-20131114git9f0c53f

Previously, when you did a btrfs fi show, you got a list with one output 
for each btrfs storage volume whether it was a single device or 
multi-device volume.

Now, I get multiple outputs for each storage volume.  For example, I 
have a system with two SSDs as one btrfs storage volume and two USB 
round-and-brown disks as a second btrfs storage volume.  Each has three 
subvols defined and mounted.

Previously, I got two outputs; one for each volume.

Now I get three outputs for the SSD storage volume and SIX outputs for 
the out volume.

Is this a bug or a feature?  If it is a feature, what is it telling me?
