This series includes a total of 27 patches, to align minmax.h of v5.15.y with v6.17-rc6.

The set consists of 24 commits that directly update minmax.h:

1. 92d23c6e9415 ("overflow, tracing: Define the is_signed_type() macro once")

But this isn't in 5.15.y, so how is this syncing things up?

I'm all for this, but I got confused here, at the first commit :)

Some of these are also only in newer kernels, which, as you know, is generally a bad thing (i.e. I can't take patches only for older kernels.)

I want these changes, as they are great, but can you perhaps provide patch series for newer kernels first so that I can then take these?
