tools lib traceevent: Rename pevent_register / unregister APIs

2018-08-13T18:27:35Z

In order to make libtraceevent into a proper library, variables, data structures and functions require a unique prefix to prevent name space conflicts. That prefix will be "tep_" and not "pevent_". This changes APIs: pevent_register_print_function, pevent_unregister_print_function, pevent_register_event_handler, pevent_unregister_event_handler, pevent_register_function, pevent_register_trace_clock Signed-off-by: Steven Rostedt Cc: Andrew Morton Cc: Peter Zijlstra Cc: Yordan Karadzhov (VMware) Cc: linux-trace-devel@vger.kernel.org Link: http://lkml.kernel.org/r/20180808180702.524813185@goodmis.org Signed-off-by: Tzvetomir Stoyanov (VMware) Signed-off-by: Arnaldo Carvalho de Melo

The timer handlers should be unregistered when the plugin is unloaded otherwise they'll try to access invalid memory.

tools lib traceevent: Use pevent_print_func_field in hrtimer_start handler

2013-12-04T18:36:50Z

The pevent_print_func_field function encompasses all the functionality used in the hrtimer_start handler. Change the handler to use this function. This also unifies the function field output with the hrtimer_expire_entry handler.

Backporting hrtimer plugin.
