The case for automated testing
Linux moves fast
Thousands of new commitsper week
Thousands of potential newbugs per week
Its better if theyre spot onquickly

Roadmap
Test soon, test frequently
Linux development anddeployment
Months from patchsetaccepted to user runningcode
Submaintainers are good,but not perfect
More testing made beforecode gets to maintainers is awin
