    md: move GET_BITMAP_FILE ioctl out from mddev_lock. · 4af1a041
    NeilBrown authored
    It makes more sense to report bitmap_info->file, rather than
    bitmap->file (the later is only available once the array is
    active).
    
    With that change, use mddev->lock to protect bitmap_info being
    set to NULL, and we can call get_bitmap_file() without taking
    the mutex.
