Function instance_set() expects to enable event 'sched_switch', so we should set 1 to its 'enable' file.
Testcase passed after this patch: # ./ftracetest test.d/instances/instance-event.tc === Ftrace unit tests === [1] Test creation and deletion of trace instances while setting an event [PASS]

Good catch!
Fixes: 91e6f1ce8657 ("ftracetest: Add instance created, delete, read and enable event test")
It seems this tests internally broken but the result is same because this disabled error checking ('set +e').
