      [4/13/14, 3:46:55 AM] Alex Zhuravlev: mdc_read_page() enqueues a lock with IT_READDIR, but then in mdc_get_rpc_lock():

      static inline void mdc_get_rpc_lock(struct mdc_rpc_lock *lck,
				    struct lookup_intent *it)
{
	ENTRY;

	if (it != NULL && (it->it_op == IT_GETATTR || it->it_op == IT_LOOKUP ||
			   it->it_op == IT_LAYOUT))
		return;

      [4/13/14, 3:47:30 AM] Alex Zhuravlev: so, enqueue for readdir is serialized with open/reint ?
