Subject: 3.17.1 kernel BUG at /usr/src/linux/fs/btrfs/relocation.c:2736!

Hi Yan,
I was attempting to migrate a JBOD drive set to RAID1,
so I did a balance filter, which failed because free space was missing,
then I attempted to remove a device from the set (because I also wanted
to do that more urgently than the RAID1 migration), and got:
