ocfs2: CoW a reflinked cluster when it is truncated. When we truncate a file to a specific size which resides in a reflinked cluster, we need to CoW it since ocfs2_zero_range_for_truncate will zero the space after the size(just another type of write). So we add a "max_cpos" in ocfs2_refcount_cow so that it will stop when it hit the max cluster offset. Signed-off-by: Tao Ma <tao.ma@oracle.com>
