OS: Manjaro Linux

Kernel version: 4.19.60

I copy binder.c/h, binder_alloc.c/h in linux 4.19.60 source code and overwrite binder.c/h in this projcet. Then I enter driver/binder folder and execute make command like following:

$ uname -r
4.19.60-1-MANJARO
$ cd driver/binder
$ make
make -C /lib/modules/4.19.60-1-MANJARO/build V=0 M=$PWD
make[1]: 进入目录“/usr/lib/modules/4.19.60-1-MANJARO/build”

$ sudo insmod binder_linux.ko

following is systemd/journal output:

How to solve this unknown symbol problem?
