During [MAINTAINERS SUMMIT] & [TECH TOPIC] Improve regression tracking discussion, it was brought to my attention that kselftest lacks support for make O=dir use-case which is used by several developers to relocate objects and keep the source tree clean. I mentioned in thread that I would take a look at what it takes to support it and here is the patch series that does that. This 11 patch series consists of fixes to get "make O=dir kselftest" use-case working, extending the existing KBUILD_OUTPUT support. Majority of the changes are made to kselftest common infrastructure. Some test make files are changed as needed to address the custom build and run_tests. -- futex has sub-directories which require custom build and run_tests. -- sync test needed a few changes to make use of lib.mk as much as possible and still be able to run its custom build sequence. With this series the following ways to build and run kselftest is possible: -- Build all and Relocate objects to /tmp/kselftest and run tests: make O=/tmp/kselftest kselftest or make KBUILD_OUTPUT=/tmp/kselftest kselftest -- Build TARGETS and Relocate objects to /tmp/kselftest and run tests: make O=/tmp/kselftest TARGETS="futex sync size" kselftest or make KBUILD_OUTPUT=/tmp/kselftest TARGETS="futex sync size" kselftest -- Clean tests: make O=/tmp/kselftest kselftest-clean or make KBUILD_OUTPUT=/tmp/kselftest kselftest-clean All existing use-cases documented in Documentation/dev-tools/kselftest.rst are still supported.
