This oops happens during a "btrfs filesystem balance /" immediately after the following messages in dmesg:
[18909.687127] btrfs: relocating block group 511130468352 flags 1

The "btrfs filesystem balance /" process also crashes. I deleted all files with an inode numbered from 414-418, but a rebalance still oopses and reports an inode in that range.
