Please don't merge these just yet. They need to be tested first. I don't
want to be in a position where the lustre client is totally not usable
like in the past. That kind of breakage makes no one want to use the
lustre client. We have a test suite for these kinds of changes. Neill do
you know how to test your patches with the test suite? Also I have been
working on several things for the last 4 months to merge upstream. I like
to coordinate with you so we don't step on each others toes.
