Yeah, it's not in the generated files:
broonie@finisterre:~/git/linux$ grep SCX_DSQ_FLAG_BUILTIN ./tools/testing/selftests/sched_ext/build/include/vmlinux.h ./tools/testing/selftests/sched_ext/build/obj/bpftool/vmlinux.h
broonie@finisterre:~/git/linux$
I didn't actually build a kernel, if the build system needs a kernel
it's just silently not detected that it's missing?
