-The target maintains the last committed transaction for a client in
-its export for that client. If this is the first connection, then that
-last transaction value would just be zero. If there were previous
-transactions for the client, then the transaction number for the last
-such committed transaction is put in the 'pb_last_committed' field.
+'ptlrpc_body'::
+See <<struct-ptlrpc-body>> for details about the RPC descriptor. In a
+connect message the 'ptlrpc_body' field 'pb_handle', which is a
+<<struct-lustre-handle>>, is 0. That 'lustre_handle' is distinct from
+the one mentioned below. In a reply, the 'pb_handle' field has the
+value, $C_t$, uniquely identifying that target. The value $C_t$ is
+preserved in the 'imp_remote_handle' field of the client's import
+structure for this target. See <<struct-obd-import>>.
