SubjectExternal kmod build failed on KASAN-enabled kernel
Hi,

The same kmod source code can be built on KASAN-disabled kernel
(5.7.0), but after enable it with CONFIG_KASAN=y, the kmod can't build
on the new installed KASAN-enabled kernel with below error message,
seems no relevant answers for this issue with google:

root@build-ws:/home/mm/slab# make

make -C /lib/modules/5.7.0/build M=/home/mm/slab modules

make[1]: Entering directory '/home/linux-5.7'

CC [M] /home/mm/slab/tap_slab.o

MODPOST 1 modules
