Actually, ARRAY_SIZE() in ./include/linux/kernel.h is diffrent from the one defined in bpf_util.h:

./include/linux/kernel.h
#define ARRAY_SIZE(arr) (sizeof(arr) / sizeof((arr)[0]) + __must_be_array(arr))

./tools/testing/selftests/bpf/bpf_util.h
#define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0]))

__must_be_array() ensures arr is an array, which is better than the one defined in bpf_util.h

Yes, I will commit another patch.
