Subject: [PATCH v2 bpf-next 0/3] bpffs pretty print for cgroup local storage

This patchset implements bpffs pretty printing for cgroup local storage maps.

v2->v1:
  - fixed size checks in cgroup_storage_check_btf(),
  based on input from Yonghong and Martin
  - implemented and used btf_type_is_reg_int(), suggested by Martin

Roman Gushchin (3):
  bpf: pass struct btf pointer to the map_check_btf() callback
  bpf: add bpffs pretty print for cgroup local storage maps
  selftests/bpf: add btf annotations for cgroup_local_storage maps
