382 394 * The server maintains a set of state on a per client basis that
383 395 * matches that of the protocol requirements. A client's state is
384 396 * rooted with the rfs4_client_t struct of which there is one per
385 397 * client and is created when SETCLIENTID/SETCLIENTID_CONFIRM are
386 398 * received. From there, the server then creates rfs4_openowner_t
387 399 * structs for each new open owner from that client and are initiated
388 400 * at OPEN/OPEN_CONFIRM (when the open owner is new to the server).
389 401 * At OPEN, at least two other structures are created, and potentially a
390 402 * third. rfs4_state_t is created to track the association between an
391 403 * open owner and a particular file. An rfs4_file_t struct may be
392 404 * created (if the file is not already open) at OPEN as well. The
393 405 * rfs4_file_t struct is the only one that is per server and not per
394 406 * client. The rfs4_deleg_state_t struct is created in the
395 407 * instance that the server is going to provide a delegation for the
396 408 * file being OPENed. Finally, the rfs4_lockowner_t is created at the
397 409 * first use of a lock owner at the server and is a result of the LOCK
398 410 * operation. The rfs4_lo_state_t struct is then created to represent
399 411 * the relation between the lock owner and the file.
