I think Greg KH would have been wise to add a time limit on this ban. Make it a 10-year block, for example, rather than one with no specific end-date.

Imagine what happens 25 years from now as some ground-breaking security research is being done at Minnesota, and they all groan: "Right, shoot, back in 2021 some dumb prof got us banned forever from submitting patches".

Is there a mechanism for University of Minnesota to appeal, someday? Even murders have parole hearings, eventually.
