If transition to a new state could take 597c478bd9Sstevel@tonic-gate * some time, then before we effect the transition we set 607c478bd9Sstevel@tonic-gate * restarter_inst_t->ri_i.i_next_state to the target state, and afterwards we 617c478bd9Sstevel@tonic-gate * rotate i_next_state to i_state and set i_next_state to 627c478bd9Sstevel@tonic-gate * RESTARTER_STATE_NONE. So usually i_next_state is _NONE when ri_lock is not 637c478bd9Sstevel@tonic-gate * held.

To keep any other threads from grabbing ri_lock before 657c478bd9Sstevel@tonic-gate * method_thread() does, we set ri_method_thread to the thread id of the 667c478bd9Sstevel@tonic-gate * method thread, and when it is nonzero any thread with a different thread id 677c478bd9Sstevel@tonic-gate * waits on ri_method_cv. 687c478bd9Sstevel@tonic-gate * 697c478bd9Sstevel@tonic-gate * Method execution is serialized by blocking on ri_method_cv in 707c478bd9Sstevel@tonic-gate * inst_lookup_by_id() and waiting for a 0 value of ri_method_thread.
