tracing: Adding new functions for kernel access to Ftrace instances
Adding 2 new functions -
1) struct trace_array *trace_array_get_by_name(const char *name);
Return pointer to a trace array with given name. If it does not exist,
create and return pointer to the new trace array.
2) int trace_array_set_clr_event(struct trace_array *tr,
const char *system ,const char *event, bool enable);
Enable/Disable events to this trace array.
Additionally,
- To handle reference counters, export trace_array_put()
- Due to introduction of the above 2 new functions, we no longer need to
export - ftrace_set_clr_event & trace_array_create APIs.
