Description
There is no information about Innodb async IO internals, and some people seem interested.
Apparently we already have information on how many IOs are either inflight or in-completion-processing. We do have some information on how many tasks are being executed.
In principle, we can even dump every incomplete IO.
We do not currently instrument waits for "free io slot", that can result from undersizing innodb_io_read/write threads, however maybe just cache size can give a good estimate (if cache size is 0, waits happen, otherwise not)
