I think the best solution would be for Kconfig to enforce that CONFIG_COMPILE_TEST is set to =y when running 'make randconfig'. I had previously discussed this with Rong and Philip, who preferred to not enforce COMPILE_TEST=y on the lkp setup because other users doing randconfig builds might still run into the same issues. An alternative would be to just not send out emails about randconfig failures that happen only with COMPILE_TEST=n. Arnd
