AIO in 10.0-RELEASE

[Rick Miller]

Please reply directly as I am not currently subscribed to this particular
mailing list...

A user has been implementing AIO features in an application on FreeBSD
10.0-RELEASE.  They assert that, despite aio(4) stating that it is enabled
either statically (with VFS_AIO in the kernel config) or dynamically
(kldload), in their development environment there was no requirement for
either of these methods of enabling AIO.  My google-foo is failing me when
it comes to FreeBSD's AIO.

This question defies logic, but is it possible that AIO works by default in
earlier versions of 10.0 and not in more recent version of 10.0 without any
local system changes?

It is understood that AIO has recently been enabled by default in FreeBSD
10.3 and -CURRENT.  This particular scenario is applicable to 10.0.
