However, the reply is incorrect. Kselftest in-kernel tests (which is the context here) can be configured as built in instead of as a module, and built in a UML kernel. The UML kernel can boot, running the in-kernel tests before UML attempts to invoke the init process.
Um, Citation needed?
The paragraph that you quoted tells you exactly how to run a kselftest in-kernel test in a UML kernel. Just to what that paragraph says.
I don't see any evidence for this in the kselftest documentation, nor do I see any evidence of this in the kselftest Makefiles.
There exists test modules in the kernel that run before the init scripts run --- but that's not strictly speaking part of kselftests, and do not have any kind of infrastructure. As noted, the kselftests_harness header file fundamentally assumes that you are running test code in userspace.
You are ignoring the kselftest in-kernel tests.
We are talking in circles. I'm done with this thread.
