The 6.1-rc6 kernel prepatch is out for
testing.

I’m still waffling about whether there will be an rc8 or not,
leaning a bit towards it happening. We’ll see – it will make the
6.2 merge window leak into the holidays, but maybe that’s fine and
just makes people make sure they have everything lined up and
ready *before* the merge window opens, the way things _should_
work.
