Therefore, I agree this is not a real issue. > My use case was running a series of tests: (test 1) - full build with -T (test N) - short circuit with -S 2 -T ... and where it confused me was that I had created tests which were designed to fail, specifically one wanted to verify no changes found for the recountdiff change in this set. Without this patch, that test will succeed as the version glitch gets picked up as: vmlinux.o: changed function: override_release I could work around that in verification, but then I miss the *specific* failure report from klp-build. I could also run each individual test as full, but each build was taking ~6 minutes on my machine. -- Joe
