Thank you for the link. I followed the instructions in the link, and I could build kernel with clang without kAsan
However, after setting the CONFIG_KASAN to y through menuconfig, the "make CC=$CLANG_PATH/clang -j64 2>&1 | tee build.log" outputs the following errors. fs/built-in.o: In function `zisofs_readpage':
