[ 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
