Bug#674258:
Hello, my system crashed yesterday, I received the following kernel
output while running btrfs balance and copied some files using rsync.
i don't know where i report this, if kernel, git btrfs-progs, or btrfs
mailing list.
i used btrfs-progs compiled from v0.20-rc1 git version.
I hope to help reporting this, sorry for the inconvenience.
thanks.
