I checked it as well it see same thing:
- __cgroup_bpf_check_dev_permission is called in
security/device_cgroup.c under CONFIG_CGROUP_DEVICE;
- __cgroup_bpf_run_filter_sysctl is called in fs/proc/proc_sysctl.c
under CONFIG_PROC_SYSCTL;
- __cgroup_bpf_run_filter_[gs]etsockopt is called in net/socket.c under
CONFIG_NET;
All three configs are bool-s so LGTM.
