 the parent and finds source and target.  In case of exchange (with
-RENAME_EXCHANGE in rename2() flags argument) lock both.  In any case,
+RENAME_EXCHANGE in flags argument) lock both.  In any case,
 if the target already exists, lock it.  If the source is a non-directory,
 lock it.  If we need to lock both, lock them in inode pointer order.
 Then call the method.  All locks are exclusive.
