Kernel prepatch 5.17-rc6

The 5.17-rc6 kernel prepatch has beenreleased.

While things look reasonably normal, we _are_ getting pretty latein the release, and we still have a number of knownregressions. They don't seem all that big and scary, but some ofthem were reported right after the rc1 release, so they are gettinga bit long in the tooth. I'd hate to have to delay 5.17 justbecause of them, and I'm starting to be a bit worried here. I thinkall the affected maintainers know who they are.
