/*
 * STATE MACHINE RULES:
 *
 * - State change requests to an XXXX object when operating within
 * an emlxs_XXXX state management function must be made
 * using the emlxs_XXXX_state() call.
 *
 * - State change requests to an XXXX object when operating outside
 * an emlxs_XXXX state management function must be made
 * using the emlxs_XXXX_alloc(), emlxs_XXXX_free(), emlxs_XXXX_event()
 * or emlxs_XXXX_..._notify() calls.
 *
 * - emlxs_XXXX_..._notify() calls are used by routines outside
 * this fcf module to enter the state machine.
 *
 * - It is forbidden to make direct calls to emlxs_XXXX_...._action()
 * functions.  Only emlxs_XXXX_action() routines may make calls to
 * emlxs_XXXX_...._action() functions.
 *
 * - Its is forbidden to make direct calls to emlxs_XXXX_action().
 * Only emlxs_XXXX_state() and emlxs_XXXX_event() routines may make
 * calls to emlxs_XXXX_action().
 *
 * - The EMLXS_FCF_LOCK must be held before calling:
 * emlxs_XXXX_state(), emlxs_XXXX_event() and emlxs_XXXX_action().
 *
 * - All other calls touching fcftab, fcfi, vfi, vpi, rpi objects
 * must hold the EMLXS_FCF_LOCK to protect these objects.
 */

/*
 * DEBUG MESSAGE TERMINATION RULES:
 *
 * - A message should end in ">" if a thread operating outside the
 * XXXX state machine enters the XXXX state machine with a call to
 * emlxs_XXXX_event() or emlxs_XXXX_state().  This includes calls made
 * from emlxs_..._notify(), emlxs_..._mbcmpl() and emlxs_..._timer()
 * routines since they represent the beginnning of new threads.
 *
 * - A message should end in "<" if the thread is about exit
 * an emlxs_XXXX_..._action() without previously calling the
 * next emlxs_XXXX_state().  This includes the emlxs_XXXX_action()
 * and emlxs_XXXX_state() routines themselves since errors
 * in these routines represent the termination of state change
 * thread.
 *
 * - A message should end in "." if none of the previous
 * conditions apply.
