Thanks! I've attached an updated patch.


BTW based on your discussion, I thought this patch could not be merged 
anytime soon. Does that align with your understanding?

- With bgworker-based AIO, this patch could mislead users into 
underestimating the actual storage I/O load, which is undesirable.
- With io_uring-based AIO, this patch could provide meaningful values, 
but it may take some time before io_uring sees widespread adoption.
