When CONFIG_KUNIT=n, the above file is mostly just a function that
returns "NULL", however, since "NULL" is not defined: kunit/test-bug.h
includes nothing if CONFIG_KUNIT=n, bindgen is not happy about it:
./include/kunit/test-bug.h:63:67: error: use of undeclared identifier 'NULL'
, we can fix this in Rust side by adding linux/stddef.h before
kunit/test-bug.h as below, but maybe it's better fixed inside
kunit/test-bug.h?
