Hi, Chris!
I'm writing the btrfs snapshot diff tool and I would like to know, whether the
entries in a btrfs directory are ordered in some way.
I want to find missing entries in a new snapshot's directory. Can I do a "linear

mtimes and ctimes for the directory in the two snapshots.
The highest generation number in the older snapshot is 82623.
But the

generation number, it is impossible to detect a inode update.
Chris, could help us to understand b
