[PATCH bpf-next v4 0/4] selftests/bpf: convert three other cgroup tests to test_progs

From: Alexis Lothoré (eBPF Foundation)
Date: Tue Aug 13 2024 - 08:46:46 EST


Hello,
this series brings a new set of test converted to the test_progs framework.
Since the tests are quite small, I chose to group three tests conversion in
the same series, but feel free to let me know if I should keep one series
per test. The series focuses on cgroup testing and converts the following
tests:
- get_cgroup_id_user
- cgroup_storage
- test_skb_cgroup_id_user
