    Btrfs: add basic restriper infrastructure · c9e9f97b

    Add basic restriper infrastructure: extended balancing ioctl and all
    related ioctl data structures, add data structure for tracking
    restriper's state to fs_info, etc.  The semantics of the old balancing
    ioctl are fully preserved.
    
    Explicitly disallow any volume operations when balance is in progress.
