Rely on the "headers_install" target to have been run first instead. For example, here's a typical error this patch is addressing: $ make O=build -j32 kselftest-gen_tar make[1]: Entering directory '/home/kernelci/linux/build' make --no-builtin-rules INSTALL_HDR_PATH=/home/kernelci/linux/build/usr \ ARCH=x86 -C ../../.. headers_install make[3]: Entering directory '/home/kernelci/linux' Makefile:1022: ../scripts/Makefile.extrawarn: No such file or directory The source directory is determined in the top-level Makefile as ".." relatively to the "build" directory, but then the kselftest Makefile switches to "-C ../../.." so "../scripts" then points one level higher than the source tree e.g. "linux/../scripts" - which fails obviously. There is no other use-case in the kernel tree where a sub-directory Makefile tries to call a top-level make target, and it appears this isn't really a valid thing to do.

The kselftest Makefile used to try to call headers_install "backwards" but failed due to the relative path not being consistent. Now we can either run this directly: $ make O=build kselftest-all or this: $ make O=build headers_install $ make O=build -C tools/testing/selftest all The same commands work as well when building directly in the source tree (no O=) or any arbitrary path (relative or absolute).
