From: Matteo Croce <teknoraver@xxxxxxxx> Enable some BPF kfuncs and the helper bpf_current_task_under_cgroup() for program types BPF_CGROUP_*. These will be used by systemd-networkd: https://github.com/systemd/systemd/pull/32212 v4->v5: Same code, but v4 had an old cover letter v3->v4: Reset all the acked-by tags because the code changed a bit.
