+ * will send these updates to the remote MDT to be executed.
+ *
+ * Update request format
+ * magic: UPDATE_BUFFER_MAGIC_V1
+ * Count: How many updates in the req.
+ * bufs[0] : following are packets of object.
+ * update[0]:
+ * type: object_update_op, the op code of update
+ * fid: The object fid of the update.
+ * lens/bufs: other parameters of the update.
+ * update[1]:

+ * fid: The object fid of the update.
