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.
v2: 1) removed a bogus check in patch 4 2) moved buf[len] = 0 in patch 2
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
