I found that all redo log IO were synchronized since mysql8.0.
and also, there is no process for redo log io  in fil_aio_wait.
So is it possible to remove  'static AIO *s_log'

How to repeat:
just read the code

Suggested fix:
 Is it possible to remove  'static AIO *s_log'?

Hi Mr. xing,

Thank you for your bug report.

The answer to your question is that, no, that variable can not be removed since it is used for the access to the files on some operating systems.

Not a bug.
