    Btrfs: add fragment=* debug mount option · d0bd4560
    Josef Bacik authored
    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.  Thanks,
