@ggouaillardet Can you please set the labels and milestones on PRs? Thanks.

Also, this PR should probably be filed with pmix upstream, as well (if you haven't already done so).

:bot:assign: @rhc54

upstream pmix has already been updated

@ggouaillardet @jsquyres This PR is not correct. I had to make a change when we upstreamed it as it broke the upstream tarball creation. I would suggest that we pull the change from there.

ok, I will update ompi master first, and then update this pr with both commits

@rhc54 done, i back-ported the changes from upstream pmix

[jsquyres]

@rhc54 Look ok?

travis red mark is attributed to github being down.

[rhc54]

👍

I think this travis error can be ignored. Looks like something didn't install right on the container that prevents usnic provider from building during the libfabric build.
@jsquyres modulo the travis build failure, I think this is ready to go.
