I did a balance on a system that had 3.11 (yes, I know, it's old). It hung.
So, I rebooted with 3.13, and it failed in fs/btrfs/relocation
Problem #1: I cannot stop the relocation. It starts on its own as soon as I
mount the FS, and I can't stop it.
Is there a bug to fix that?
Problem #2: I rebooted with 3.15rc5, and now it's worse.
[ 1569.598026] kernel BUG at fs/btrfs/relocation.c:1064!
then leads to

I'm sure that filesystem is damaged in some way, but the kernel of course
should not crash.
I don't have this mail client setup right to send patches, can you just
go into relocation.c in build_backref_tree and remove the need_check =
false; statement and see if that fixes it. Thanks,
Josef
