Hi all, since a couple people here are using btrfs (we, fortunately, are not), I thought you might be interested in this blog entry: <http://crypto.junod.info/2012/12/13/hash-dos-and-btrfs/> Basically, it seems that if you create files with filenames that have colliding CRC32 hashes, all kind of hell breaks loose. Definitely an interesting read.
