Thanks a lot for writing all this.
At the end https://github.com/open-mpi/ompi/wiki/GitSubmodules#adding-a-new-submodule-pointing-to-a-specific-commit should "bar" be "bar50x" in line "$ git add bar" ? It seems to me that you are in opal/mca/foo and the new submodule is in "bar50x" (according to "cd opal/mca/foo/bar50x" at the beginning). There's also a "bar-50x" instead of "bar50x" in line "git submodule add --name bar-50x ...". Should the submodule name match the directory name? By the way, in https://github.com/open-mpi/ompi/wiki/GitSubmodules#updating-the-commit-that-a-submodule-refers-to you may want to rename hwloc201 into hwloc2 to avoid confusion and match the current PR.
