[Yafang Shao <laoar.shao@gmail.com>]

This is the BPF part of the series "bpf, cgroup: Add BPF support for
cgroup1 hierarchy" with adjustment in the last two patches compared
to the previous one.

v3->v4:
  - use subsys_name instead of cgrp_name in get_cgroup_hierarchy_id()
    (Tejun)
  - use local bpf_link instead of modifying the skeleton in the
    selftests
v3: https://lwn.net/Articles/949264/

Yafang Shao (6):
  bpf: Add a new kfunc for cgroup1 hierarchy
  selftests/bpf: Fix issues in setup_classid_environment()
  selftests/bpf: Add parallel support for classid
  selftests/bpf: Add a new cgroup helper get_classid_cgroup_id()
