The requirement to do "make headers" is not a keeper. Really.
The reason we added the requirement to avoid duplicate defines
such as this one added to kselftest source files. These are
error prone and hard to resolve.
In some cases, these don't become uapi and don't make it into
system headers. selftests are in a category of depending on
kernel headers to be able to test some features.
Getting rid of this dependency mean, tests will be full of local
defines such as this one which will become unmanageable overtime.
Not if we do it correctly...Please do look at the reference I provided
for how that works. Here is is again: [1].
The basic idea, which has been discussed and reviewed, is to take
very occasional snapshots and drop them into a static location where
they are available for kselftests, without disurbing other things:
$(top_srcdir)/tools/include/uapi
This has worked well so far.
The discussion should be: "How do we get rid of the dependency without
introducing local defines?" not just "Let's get rid of the dependency"
Yes. Good. We are apparently in violent agreement, because a few lines

The "make headers" is the problem, not the fact that we need to depend
on various includes. And so the solution stops requiring "make headers".
It gets the includes from a less volatile location.
Yes?
