Jordan: ktest: Automated Testing For Kernel Programmers

Daniel Jordan looks atktest on the Oracle Linux blog. "Where ktest is especiallyuseful, though, is in its ability to do these things for each patch in aseries, thereby freeing you from a significant amount of tedium. For yourchosen configs, the series will be cleanly bisectable and won't triggerupstream build bots with easily avoided errors and warningsmid-series. (Those bots are nice for less common configs though.) Codereviewers' moods improve too because each patch will stand alone with allthe necessary code."
