Hi, I have been reading cgroup v2 for device cgroup along with bpf cgroup and have some questions. For bpf cgroup, is it typical to not have a default bpf program to define "normal" behaviour? Is it fair to say that, for device cgroup in v2, if it's not for the v1 implementation as the catch-all, userspace applications like container runtimes will have to supply their own bpf program in order to get the same functionality in v1? Regards, Kenny
