I've been keeping a copy on rhlinux.redhat.com.  You can access it
via:

  cvs -d :pserver:anonymous at rhlinux.redhat.com:/usr/local/CVS login  # no password
  cvs -d :pserver:anonymous at rhlinux.redhat.com:/usr/local/CVS co libaio

I think we also need to update the test cases to use O_DIRECT, since
buffered AIO isn't really supported.  I'll work on that.  In the mean
time, I've incorporated your changes into a work branch
(jmoyer-work-branch).  When I'm happy with the regression tests (they
don't all pass for me on 2.6.24-rc7), I'll roll a new version and
build it for Fedora.

Thanks again!
