NameDescribe
tracepoint_add_funcAdd the probe function to a tracepoint.
tracepoint_remove_funcRemove a probe function from a tracepoint.* Note: only waiting an RCU period after setting elem->call to the empty* function insures that the original callback is not used anymore. This insured* by preempt_disable around the call site.
