Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features.
One of them is the full support of disconnections from the userspace introduced by commit b29fcfb54cd7 ("mptcp: full disconnect implementation").
It is possible to look for "mptcp_pm_data_reset" in kallsyms because a preparation patch added it to ease the introduction of the mentioned feature.
