[PATCH 2/2] selftests: Replace relative includes with non-relative for kselftest.h and kselftest_harness.h

[Bala-Vignesh-Reddy]

Hi Wei,

Thanks for testing and for your feedback.

Yeah, if you try to build inside a subdirectory, the top level
export may not apply, so CFLAGS don't get updated, and even if
they did, the path could be pointing to wrong location.

As the docs recommend, building selftest using TARGETS,
either from kernel source or "tools/testing/selftests/"
works fine and doesn't fail.

If you really want to build from selftests/mm/ directory then
defining KSFT_INCLUDES with a fallback in the Makefile will
resolve it, but there is no need of it if we stick with "TARGETS=mm".

Thanks
Bala Vignesh
