'available_events' is actually not required by 'test.d/event/toplevel-enable.tc' and its Existence has been tested in 'test.d/00basic/basic4.tc'. So the require of 'available_events' can be dropped and then we can add 'instance' flag to test 'test.d/event/toplevel-enable.tc' for instance. Test result show as below: # ./ftracetest test.d/event/toplevel-enable.tc === Ftrace unit tests === [1] event tracing - enable/disable with top level files [PASS] [2] (instance) event tracing - enable/disable with top level files [PASS] # of passed: 2 # of failed: 0 # of unresolved: 0 # of untested: 0 # of unsupported: 0 # of xfailed: 0 # of undefined(test bug): 0 Link: https://lore.kernel.org/r/20230509203659.1173917-1-zhengyejian1@huawei.com Signed-off-by: Zheng Yejian <zhengyejian1@huawei.com> Acked-by: Steven Rostedt (Google) <rostedt@goodmis.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
