[1] https://patchwork.kernel.org/project/mptcp/patch/b6b53fd730a0edd0024963468d078488ad5e67aa.1729588019.git.tanggeliang@kylinos.cn/ v2: - squash patches 5,6 of v1 into one. - patch 3, use lockdep_assert_held instead of spin_is_locked. - update patch 5 to make it run normally in btf-debug mode. Another bpf_iter for BPF path manager to traverse all address entries on userspace_pm_local_addr_list of an MPTCP socket is added in this set. Userspace pm tool is needed by the self test, so add pm_nl_ctl link in patch 1.
