- * tb_flush() - flush all translation blocks

+ * queue_tb_flush() - add flush to the cpu work queue
+ * @cs: CPUState
  *
- * Used to flush all the translation blocks in the system. Sometimes
- * it is simpler to flush everything than work out which individual
- * translations are now invalid and ensure they are not called
- * anymore.
- *
- * tb_flush() takes care of running the flush in an exclusive context
- * if it is not already running in one. This means no guest code will
- * run until this complete.
+ * Flush all translation blocks the next time @cs processes the work queue.
+ * This should generally be followed by cpu_loop_exit(), so that the work
+ * queue is processed promptly.
