The 5.17-rc6 kernel prepatch has been
released.

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