Hi,
I have a 11G btrfs file system where "btrfs-vol -b" get stuck in a
loop. The "found 7 extents" messages and heavy disk io continues until I
reboot:
[26223.544037] btrfs: relocating block group 42079027200 flags 36
[26228.082740] btrfs: found 2457 extents
[26228.104515] btrfs: relocating block group 41407938560 flags 1
[26228.423981] btrfs: found 124 extents
[26229.514583] btrfs: found 124 extents
[26229.544160] btrfs: found 7 extents
[26229.812494] btrfs: found 7 extents
[26230.453720] btrfs: found 7 extents

[26231.383321] btrfs: found 7 extents
[26231.652815] btrfs: found 7 extents
...
The error is repeatable. btrfsck does not report any errors:

The kernel is Linus' master from two days ago, and seems to have all the
latest btrfs code merged.
