Seconded. I almost hesitate to say it, but we should probably test on 
zfs too.

btrfs is in the kernel. There's a 
on my CentOS 6.5 box. You can get btrfs-progs from epel.

A cursory look at the diff between the RHEL6.5 .../fs/btrfs source and 
the Fedora .../fs/btrfs source doesn't look too different; if we're 
worried about the relative stability of btrfs. It's my understanding 
that it was only the lack of an fsck utility that was hindering its 
adoption in RHEL.

I'd say we ought to test on both RHEL/CentOS and Fedora. With our 
limited resources we just need to prioritize accordingly.

And if there's some concern about the diff between btrfs-progs-0.20.0 in 
RHEL/CentOS versus btrfs-progs-3.12-1 in Fedora, I suspect we can build 
btrfs-progs-3.12-1 for RHEL and CentOS.
