Unique final message of InnoDB during shutdown

Please create some unique message to be written by InnoDB into the server error log

which signals that InnoDB will stop its activity (processes and/or threads) immediate.

Such a message would be a significant advantage for QA when classifying suspicious effects.

One example of behaviour in 10.6

[Note] ... /bin/mysqld (initiated by: root[root] @ localhost [127.0.0.1]): Normal shutdown

...

Note] InnoDB: Starting shutdown...

[Note] InnoDB: Dumping buffer pool(s) to ... data/ib_buffer_pool

[Note] InnoDB: Buffer pool(s) dump completed at 201202 19:59:02

[Note] InnoDB: Shutdown completed; log sequence number 3153035; transaction id 4930

[Note] InnoDB: Removed temporary tablespace data file: "ibtmp1"

[Note] ... bin/mysqld: Shutdown complete

I would prefer to have an order of InnoDB related messages like

  [Note] InnoDB: Removed temporary tablespace data file: "ibtmp1" 

        or whatever InnoDB likes to tell

  [Note] InnoDB: Shutdown completed;  <and whatever extra info in the same line>

  < no line written by InnoDB because it has really finished its work>

  [Note] ... bin/mysqld: Shutdown complete

for all currently supported and future MariaDB versions
