I think Btrfs was depreciated in favor of XFS for RHEL 7:

     [W]e're looking to make XFS the new default for boot, for root and 
for user data predictions because it's a better match for our enterprise 
customers than btrfs seems to be.

So maybe it started with 6.4 kernels, or maybe there was just a bug in 
initial kernel.

Also, there could be two causes:

1. You tried to use btrfs partitions with only formatting them.

2. You used GPT partition table that 6.4 can not see properly?
