I've caught this type of corruption in the wild. The big rsync backup
always ends with a kernel crash due to BUG() statement in
ctime.h:1779. After applying this patchset and running scrub I've got
following messages:

[sivan@fruestuck ~]$ dmesg | grep "invalid extent inline"
[ 8812.428673] eb 4631634034688(tree block) invalid extent inline ref type 0
[ 8812.429148] BTRFS error (device sdb1): scrub: extent
2994741510144(0x2b944810000) has an invalid extent inline ref type,
ignored.
[ 8812.430086] eb 4631634034688(tree block) invalid extent inline ref type 0
[ 8812.430569] BTRFS error (device sdb1): scrub: extent
2994741559296(0x2b94481c000) has an invalid extent inline ref type,
ignored.

How to find the cause of the corruption? Should I try to fix it, or it
is not dangerous for the filesystem? If I should, how to do that?
