OK...slack is 0, so there wasn't anything weird with underlying device
sizes going on.
There's 3 entries for "Data,RAID6" because there are three stripe widths:
12 disks, 6 disks, and 4 disks, corresponding to the number of disks of
each size. Unfortunately 'dev usage' doesn't say which one is which.
RFE: improve 'dev usage' to show these details.
As a user I'd look at this output and assume a bug in btrfs-tools
because of the repeated conflicting information.
