[PATCH bpf-next 1/3] selftests/bpf: tc_helpers: Add create_and_open_tid_ns()
From: Bastien Curutchet (eBPF Foundation)
Date: Mon Feb 17 2025 - 07:38:08 EST
Add a create_and_open_tid_ns() helper that creates a new network
namespace and open it.
Use the append_tid() helper to ensure the uniqueness of the namespace
name.
