That's old stuff. https://lore.kernel.org/all/20230620045919.492128-1-suhui@xxxxxxxxxxxx/ We need to try rebuild again. Don't do a make clean. It will fail fast now. make -j`nproc` -k \ CHECK="/PATH/TO/smatch --succeed -p=kernel --file-output" \ C=1 bzImage modules 2>&1 | tee smatch_compile.warns grep Error smatch_compile.warns > > However, when I tried to make allyesconfig and make -j32, it builds > successfully. This is really weird.
