To: rostedt; +Cc: linux-trace-devel
Input arguments of libtraceevent APIs are renamed from "struct
tep_handle *pevent" to "struct tep_handle *tep". This makes the API
consistent with the chosen naming convention: tep (trace event parser),
instead of the old pevent.

From: Tzvetomir Stoyanov @ 2019-04-05 14:03 UTC (permalink / raw)
To: rostedt; +Cc: linux-trace-devel
The member "pevent" of the struct tep_event is renamed to "tep". This
makes the struct consistent with the chosen naming convention:
tep (trace event parser), instead of the old pevent.

From: Tzvetomir Stoyanov @ 2019-04-05 14:03 UTC (permalink / raw)
To: rostedt; +Cc: linux-trace-devel
"pevent" to "tep" renaming of:
- all "pevent" input arguments of libtraceevent internal functions.
- all local "pevent" variables of libtraceevent.
This makes the implementation consistent with the chosen naming
convention, tep (trace event parser), and will avoid any confusion with
the old pevent name
