[ Upstream commit f4e4ada586995b17f828c6d147d1800eb1471450 ]
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]
# of passed: 1
# of failed: 0
# of unresolved: 0
# of untested: 0
# of unsupported: 0
# of xfailed: 0
# of undefined(test bug): 0
