I think the main purpose of the time to BUG list is demonstrating the value in file system fuzzing. That you can have things like NTFS, HFS+, XFS that have been around a long time, lots of money spent on their development, subject to massive piles of real world tests and yet in just a couple hours hit a BUG, says something good about the technique. Not bad about the filesystem. Even in the Btrfs case, it may just be a function of the code having lots of awareness of where bodies are buried, so it hits BUG rather than continuing in a bad way and blowing up later. But as yet not enough testing to figure out all the path ways for hitting those bugs. It may explain the edge cases that still pop up with Btrfs, where I go "umm yeah I use this every day and never experience anything like that" but another user suddenly hits something that's a "wow" moment.
