This got triggered by an rsync I think. I'm not sure which of my btrfs FS
has the issue yet since BUG_ON isn't very helpful as discussed earlier.
[160562.925463] parent transid verify failed on 2776298520576 wanted 41015 found
18120
[160562.950297] ------------[ cut here ]------------
[160562.965904] kernel BUG at fs/btrfs/locking.c:269!
But shouldn't messages like 'parent transid verify failed' print
which device
this happened on to give the operator a hint on where the problem is?
Could someone do a pass at those and make sure they all print the device
ID/name?
Bug below:
