    HAMMER VFS - Force reading from the block device when live dedup is enabled
    
    * Attempting to access the vnode's buffer cache is currently not MPSAFE
      and can cause crashes so don't try to do that.  Use the block device
      instead.
    
    * It is suggested but not required that vfs.hammer.double_buffer mode also
      be enabled if you use vfs.hammer.live.deup.
