6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Geliang Tang <geliang.tang@xxxxxxxx> commit bdbef0a6ff10603895b0ba39f56bf874cb2b551a upstream. To avoid duplicated code in different MPTCP selftests, we can add and use helpers defined in mptcp_lib.sh. Export kill_wait() helper in userspace_pm.sh into mptcp_lib.sh and rename it as mptcp_lib_kill_wait(). It can be used to instead of kill_wait() in mptcp_join.sh. Use the new helper in both scripts.
