It's even crazier; they sometimes backport changes to their kernel that the LTS kernels don't get. We use a custom kernel module that contains a bunch of #if #endif blocks that check the kernel version for stuff that changed. Doesn't work on RedHat since you actually need the branch that's for more recent kernels in some places.

Isn’t the whole autoconf stuff supposed to avoid the need for if macro soup, by using feature detection?

There would be cleaner ways to achieve this, maybe not specifically autoconf since I think that's more tailored towards "normal" (user space) stuff.

Macros are convenient to quickly check the version in your code without adding another layer of tooling... Until you end up with said macro soup of course.

It's actually a legacy module we're about to phase out for 5.x so don't worry too much. The new and shiny replacement will probably use git branches for whenever something changes.
