That prefix will be "tep_" and not "pevent_". This changes static variables and functions in event-parse.c: pevent_func_params, __pevent_parse_format, __pevent_parse_event, pevent_error_str, pevent_search_event Signed-off-by: Tzvetomir Stoyanov (VMware) Cc: Andrew Morton Cc: Peter Zijlstra Cc: Yordan Karadzhov (VMware) Cc: linux-trace-devel@vger.kernel.org Link: http://lkml.kernel.org/r/20180808180703.575392642@goodmis.org Signed-off-by: Steven Rostedt Signed-off-by: Arnaldo Carvalho de Melo --- tools/lib/traceevent/event-parse.c | 54 +++++++++++++++++++------------------- 1 file changed, 27 insertions(+), 27 deletions(-) diff --git a/tools/lib/traceevent/event-parse.c b/tools/lib/traceevent/event-parse.c index f723c088acca..6313e32680ff 100644 --- a/tools/lib/traceevent/event-parse.c +++ b/tools/lib/traceevent/event-parse.c @@ -92,9 +92,9 @@ struct event_handler { void *context;
