Ocfs2/move_extents: move/defrag extents within a certain range. the basic logic of moving extents for a file is pretty like punching-hole sequence, walk the extents within the range as user specified, calculating an appropriate len to defrag/move, then let ocfs2_defrag/move_extent() to do the actual moving. This func ends up setting 'OCFS2_MOVE_EXT_FL_COMPLETE' to userpace if operation gets done successfully.
