      If object is on remote MDT, PDO lock is not supported, because two locks can't be fetched in one RPC right now, once the batch processing framework is ready, these two locks can be enqueued in a batch. This will greatly reduce conflicts in parent lock, and improve remote directory creation/unlink performance. Since filesystem-wide default directory layout is set by default, this will speed up mdtest directory creation/unlink test.
