Linux kernel team rejects University of Minnesota researchers’ apology

UMN researchers probed for weaknesses in patch approval—Greg K-H wasn’t amused.

Last week, senior Linux kernel developer Greg Kroah-Hartman announced that all Linux patches coming from the University of Minnesota would be summarily rejected by default.

This policy change came as a result of three University of Minnesota researchers—Qiushi Wu, Kangjie Lu, and Aditya Pakki—embarking on a program to test the Linux kernel dev community's resistance to what the group called "Hypocrite Commits."
