+ * It is relative easy. Be as one of remote MDT-objects, the slave MDT-object
+ * is linked under /REMOTE_PARENT_DIR with the name of its FID string.
+ * We can locate the slave MDT-object via lookup the /REMOTE_PARENT_DIR
+ * directly. Please check osd_fid_lookup().
+ *
+ * 2) The slave MDT-object and the master MDT-object reside on the same MDT.
+ * Under such case, during lookup the master MDT-object, we will lookup the
+ * slave MDT-object via readdir against the master MDT-object, because the
+ * slave MDT-objects information are stored as sub-directories with the name
+ * "${FID}:${index}". Then when find the local slave MDT-object, its OI
+ * mapping will be recorded. Then subsequent osd_fid_lookup() will know
