Transaction Number ~~~~~~~~~~~~~~~~~~ [[transno]] Every transaction that modifies a target is assigned a 'transaction number'. The transaction numbers for a given target are assigned in a strictly increasing sequence. In this way, the transactions from all clients are strictly ordered. The server assigns the next value in the target's sequence and informs the client of the value in the 'pb_transno' field of the 'ptlrpc_body' of its reply to the client's request. See <>.
