As I already told you, it is NOT correct to say that they don't work at
all and, in fact, just hides the real thing that needs fixing. That isn't
good; if you said that "oh, offsets don't work" then someone would be a
lot more likely to look at it than if you say "oh, they just don't work
period".
And, at this point, the only thing that I would see wrong that didn't work
in your test program is the offsets.

/sys/kern/vfs_aio.c has the aio_* stuff, but I think the problem is
actually down lower in things like vn_write in vfs_vops.c.
It doesn't look too hard to fix, but I haven't had a chance to try it yet.
