Bug Description

This oops happens during a "btrfs filesystem balance /" immediately after the following messages in dmesg:

[18909.687127] btrfs: relocating block group 511130468352 flags 1
[18910.145061] btrfs_readpage_end_io_hook: 18 callbacks suppressed

[18910.310181] btrfs csum failed ino 414 off 9949184 csum 1385781806 private 1385781805

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.
