From f98d6dd1e79d4b04c2e13e91a9348473cfa805a6 Mon Sep 17 00:00:00 2001 From: Guo Zhengkui Date: Tue, 15 Mar 2022 21:01:26 +0800 Subject: selftests/bpf: Clean up array_size.cocci warnings Clean up the array_size.cocci warnings under tools/testing/selftests/bpf/: Use `ARRAY_SIZE(arr)` instead of forms like `sizeof(arr)/sizeof(arr[0])`. tools/testing/selftests/bpf/test_cgroup_storage.c uses ARRAY_SIZE() defined in tools/include/linux/kernel.h (sys/sysinfo.h -> linux/kernel.h), while others use ARRAY_SIZE() in bpf_util.h.
