as an extra parameter.  This is needed since we need to know the size
      before we can map the mft record and our callers always know it.  The
      reason we cannot simply read the size from the vfs inode i_size is
      that this is not necessarily uptodate.  This happens when
      ntfs_attr_make_non_resident() is called in the ->truncate call path.
