There will be a build warning -Wunused-function if CONFIG_CGROUP_BPF
isn't defined, since the only user is inside #ifdef CONFIG_CGROUP_BPF:
kernel/bpf/syscall.c:1229:12: warning: ‘bpf_prog_attach_check_attach_type’
defined but not used [-Wunused-function]
static int bpf_prog_attach_check_attach_type(const struct bpf_prog *prog,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Current code moves function bpf_prog_attach_check_attach_type inside
ifdef CONFIG_CGROUP_BPF.
