Commitb2d35fa5fc("selftests: add headers_install to lib.mk") added khdr target to run headers_install target from the main Makefile. The logic uses KSFT_KHDR_INSTALL and top_srcdir as controls to initialize variables and include files to run headers_install from the top level Makefile. There are a few problems with this logic. 1. Exposes top_srcdir to all tests 2. Common logic impacts all tests 3. Uses KSFT_KHDR_INSTALL, top_srcdir, and khdr in an adhoc way. Tests add "khdr" dependency in their Makefiles to TEST_PROGS_EXTENDED in some cases, and STATIC_LIBS in other cases. This makes this framework confusing to use. The common logic that runs for all tests even when KSFT_KHDR_INSTALL isn't defined by the test. top_srcdir is initialized to a default value when test doesn't initialize it. It works for all tests without a sub-dir structure and tests with sub-dir structure fail to build. e.g: make -C sparc64/drivers/ or make -C drivers/dma-buf ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory make: *** No rule to make target '../../../../scripts/subarch.include'. Stop. There is no reason to require all tests to define top_srcdir and there is no need to require tests to add khdr dependency using adhoc changes to TEST_* and other variables. Fix it with a consistent use of KSFT_KHDR_INSTALL and top_srcdir from tests that have the dependency on headers_install. Change common logic to include khdr target define and "all" target with dependency on khdr when KSFT_KHDR_INSTALL is defined. Only tests that have dependency on headers_install have to define just the KSFT_KHDR_INSTALL, and top_srcdir variables and there is no need to specify khdr dependency in the test Makefiles.
