Not > sure why this error is popping up. Do a 32-bit build and you'll see it. With GCC 12.1.0, ARCH=i386 defconfig + CONFIG_BLK_DEV_NULL_BLK=y + CONFIG_BLK_DEV_ZONED=y reproduces it for me: $ make -skj"$(nproc)" ARCH=i386 defconfig menuconfig all ld: drivers/block/null_blk/zoned.o: in function `null_init_zoned_dev': zoned.c:(.text+0x112e): undefined reference to `__umoddi3' ... roundup() does a plain division with a 64-bit dividend, which will cause issues with 32-bit architectures. I suspect that you should really be using DIV_ROUND_UP_SECTOR_T() for the nr_zones calculation or maybe one of the other rounding macros in include/linux/math.h but I am not sure. Cheers, Nathan
