- * no special handle for remote dir, which needs to fetch both LOOKUP
- * lock on parent, and then UPDATE lock on child MDT, which makes all
- * complicated because this is done async. So only LOOKUP lock is
- * fetched for remote dir, but considering remote dir is rare case,
- * and not supporting it in statahead won't cause any issue, just leave
- * it as is.
+ * remote object needs two RPCs to lookup and getattr, considering the
+ * complexity don't support statahead for now.
