Matt Auld is on vacation, and the other issue is that the tree where this
is from isn't in linux-next. So will take a bit to get sorted in

Those warnings are now coming from Linus' tree (some time before
v5.14-rc1).  I first mentioned them on June 3.

Doc build is taking absolutely forever here, but I think I have the
