It appears to be a macro defined in include/trace/events/shed.h.
35 TRACE_EVENT(sched_kthread_stop_ret,

37 TP_PROTO(int ret),

39 TP_ARGS(ret),
40
41 TP_STRUCT__entry(
42 __field( int, ret )
43 ),
44
45 TP_fast_assign(
46 __entry->ret = ret;
47 ),
48
49 TP_printk("ret=%d", __entry->ret)

Subject: what is trace_sched_kthread_stop_ret used for?
Dear all:
i saw there is a function called "trace_sched_kthread_stop_ret" in some place of kernel.
but I found it is empty function.
http://lxr.linux.no/linux+v3.1.5/+code=trace_sched_kthread_stop_ret
if it is empty, why we still keep it in kernel?
