Seems to be broken.  This breaks mounting my raid6 partition:

[   87.290698] attempt to access beyond end of device
               md0: rw=4096, want=13996467328, limit=6261202944
[   87.293371] attempt to access beyond end of device
               md0: rw=4096, want=13998564480, limit=6261202944
[   87.296045] BTRFS warning (device md0): couldn't read tree root
[   87.300056] BTRFS error (device md0): open_ctree failed

Reverting it goes back to the -rc7 behaviour where it mounts fine.
