Without knowing what state you want to trace, I have no idea how to
implement it. But what you could do is to write a module and basically
implement your own trace on/off, as tracing_on/off can be done by
modules
tracing_on()
tracing_off()
and you can create your own tracepoint in the module that traces the
state you want to trace. Or just use trace_printk().
tracing_on();
trace_printk("on state = %d\n", state);
[...]
trace_printk("off state = %d\n", state);
tracing_off();
