The 5.16-rc5 kernel prepatch is out for
testing.
Do give it a good testing – with the holidays coming up, things are
probably going to slow down both on the development and testing front,
and as a result I expect that I will also extend the rc series by
another week not because it’s necessarily needed (too early to tell,
but doesn’t feel that way), but simply because nobody will want to
open the next merge window immediately in the new year.
