Subject: [PATCH bpf-next 0/4] cgroup bpf auto-detachment

This patchset implements a cgroup bpf auto-detachment functionality:
bpf programs are attached as soon as possible after removal of the
cgroup, without waiting for the release of all associated resources.

Patches 2 and 3 are required to implement a corresponding kselftest
in patch 4.

Roman Gushchin (4):
  bpf: decouple the lifetime of cgroup_bpf from cgroup itself
  selftests/bpf: convert test_cgrp2_attach2 example into kselftest
  selftests/bpf: enable all available cgroup v2 controllers
  selftests/bpf: add auto-detach test
