[PATCH net-next 08/11] selftests: mptcp: make evts global in userspace_pm

From: Matthieu Baerts
Date: Wed Nov 30 2022 - 09:08:45 EST


From: Geliang Tang <geliang.tang@xxxxxxxx>

This patch makes server_evts and client_evts global in userspace_pm.sh,
then these two variables could be used in test_announce(), test_remove()
and test_subflows(). The local variable 'evts' in these three functions
then could be dropped.

Also move local variable 'file' as a global one.
