This is similar to the > default behaviour of make headers_install. A normal user can install tests at any location they choose by overriding the default path. For example: INSTALL_MOD_PATH=/tmp make kselftest_install will install under tmp. The approach I used also ties test installs to kernel release. This addresses an important use-case for kernel developers that want to compare results from release to release. The use-case for any user to be able to install tests at any location is addressed by the above example. I would like these two above use-cases continued to be supported, especially the one that tries the test installs to kernel release. Another goal is to keep changes to the main Makefile minimal and the rest of the install support belongs under selftests/Makefile and any other include file (like the one you proposed). The patch I have in patch v4 addresses the use-cases mentioned above. I do like the lib.mk approach in general and I am going to review that patch and give you feedback. thanks, -- Shuah -- Shuah Khan Sr. Linux Kernel Developer Open Source Innovation Group Samsung Research America (Silicon Valley) shuahkh@xxxxxxxxxxxxxxx | (970) 217-8978 -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
