I'd be willing to bet the issue is in your io_syscall6 implementation.
You pass in arg5 where arg6 should be used.  Don't feel bad, it took me
the better part of today to figure that out.  :)

Here's an incremental diff on top of what you've posted.  Feel free to
fold it into your patch (and format however you like).  You can find the
libaio changes in my 'aio-poll' branch:
  https://pagure.io/libaio/commits/aio-poll

These changes were run through the libaio test harness, 64 bit and 32
bit, so the compat system call was tested.

Oops, yes.  Although I prefer the copy_from_user version, this is what
I had:

Much cleaner.

Thanks!
Jeff
