+ * MDT-object, we will do name based lookup (for the striped directory itself)
+ * firstly, during such process we can setup the correct OI mapping for the
+ * master MDT-object. But it will be trouble for the slave MDT-object. Because
+ * the client will not trigger name based lookup on the MDT to locate the slave
+ * MDT-object before locating item under the striped directory, then when
+ * osd_fid_lookup(), it will find that the OI mapping for the slave MDT-object
+ * is invalid and does not know what the right OI mapping is, then the MDT has
+ * to return -EINPROGRESS to the client to notify that the OI scrub is rebuiding
+ * the OI file, related OI mapping is unknown yet, please try again later. And
+ * then client will re-try the RPC again and again until related OI mapping has
+ * been updated. That is quite inefficient.
+ *
+ * To resolve above trouble, we will handle it as the following two cases:
+ *
+ * 1) The slave MDT-object and the master MDT-object are on different MDTs.
+ * 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
+ * the correct OI mapping for the slave MDT-object. */
