vfs.aio tuning question

Couldn't find any real explanation of these parameters online, but I
noticed they appear to have disappeared in 4.8.
I have a 4.6 system that shows the following parameters when sysctl -a
Now, I'm pretty sure these have something to do with asynchronous I/O,
and I'm under the impression this is a bad thing to use. It appears
this 4.6.2-RELEASE system is using it, but I don't know how to verify
it or how to be sure it's not going to wreck something.
If possible, I'd like someone to point me to a reference that
describes the async features in some detail and particularly these
parameters. Also, are they really gone from 4.8 or do they have to be
'turned on' somehow - and when is this an acceptable configuration?
Thanks a lot folks.
