Btrfs: add fragment=* debug mount option In tracking down these weird bitmap problems it was helpful to artificially create an extremely fragmented file system. These mount options let us either fragment data or metadata or both. With these options I could reproduce all sorts of weird latencies and hangs that occur under extreme fragmentation and get them fixed.
