Kernel prepatch 6.16-rc1

Linus has released 6.16-rc1 and closed the
merge window for this release.

I think we had a fairly normal merge window, although I did get the
feeling that there were a few more 'late straggler' pull requests
than usual. Not to a huge degree, but there was definitely an
upward bump at the end of the second week.

But on the whole, all the stats look pretty normal.
