--- Comment #2 from David Smith <dsmith at redhat dot com> ---
Note that the relay host/guest functionality also doesn't work on RHEL6, RHEL7
or any current fedora or rawhide kernels. The only place this works is on
RHEL5-era kernels.

Perhaps we should just deprecate this functionality (and remove its
documentation from the manpage)?

The least thing we could do here would be to change the sharedbuf.exp test case
to issue KFAILS (and reference this bug report).

(One *ugly* solution here would be to bypass the module exporting mechanism
here and use kallsyms_lookup_name() to find the function. The problem with this
approach is that wouldn't update the relay host module's reference count,
making it possible to remove the relay host module before the relay guest
module. We might be able to update the relay host module's reference count
ourselves but we don't really know the module's name and there are probably
several time-of-check-to-time-of-use (TOCTTOU) problems lurking there.)
