Could you please provide the exact steps? Sure, here are the exact commands I ran to reproduce for S390_UNWIND_SELFTEST. Note that I'm on x86-64 and cross-compiling for s390: 1. Start from a minimal configuration: 'make ARCH=s390 CROSS_COMPILE=s390x-unknown-linux-gnu- allnoconfig' 2. Enter menuconfig: 'make ARCH=s390 CROSS_COMPILE=s390x-unknown-linux-gnu- menuconfig' 3. Set CONFIG_KUNIT=y 4. Set CONFIG_KUNIT_ALL_TESTS=y 5. Check '.config', and see that S390_UNWIND_SELFTEST is still disabled The steps to reproduce for S390_MODULES_SANITY_TEST are the same, but you also need to enable MODULES because of the additional dependency. > I do appreciate your effort to bring a new tool!

IOW, once it is in the tree, it is fine to mention it: Thanks :) Separately, I checked with Greg, and he says that: 1. it is a requirement to acknowledge tool usage, but 2. this patch (and others like it) shouldn't have the Fixes tag. So I will resubmit this patch without "Fixes", but still acknowledging the tool, see also: https://lore.kernel.org/all/2026050728-construct-tingle-0852@gregkh/ - Julian Braha
