We do not go through the dist-* targets: git-publish.sh runs build_configs.sh directly, RHJOBS="$(nproc)" ARCH_MACH=x86_64 ./build_configs.sh kernel rhel RHJOBS="$(nproc)" ARCH_MACH=um ./build_configs.sh kernel rhel so ENABLE_WERROR is never set there, and the um config keeps WERROR off. The UML kernel does not build with -Werror for now anyway. lib/iomap.c gets -Wmissing-prototypes for ioread64_lo_hi() and its siblings, as UML includes asm-generic/iomap.h before readq is defined. Upstream fixed it in dc90c890363d3 ("asm-generic/io.h: rework split ioread64/iowrite64 helpers", v6.15), but the rework touches the generic I/O headers of every architecture, too intrusive to bring in for the sake of a test kernel. What your note did show is that our x86_64 kernels are built without -Werror at all, unlike RHEL's: with no ENABLE_WERROR in git-publish.sh, CONFIG_WERROR and CONFIG_KVM_WERROR stay off. That is not good, and we will fix it with override files in custom-overrides/generic, which the um layer still overrides with WERROR off: https://virtuozzo.atlassian.net/browse/VSTOR-151903 > Updated https://bitbucket.org/virtuozzocore/hci-tests.vhistrg/pull-requests/9241 with follow-ups: Pass kasan_multi_shot, handle printk timestamp, removed KASAN report filter.
