From dc05ebf373e9e66c27aae0d9059e5d4ac56f3be0 Mon Sep 17 00:00:00 2001 From: "Tzvetomir Stoyanov (VMware)" Date: Wed, 8 Aug 2018 14:03:03 -0400 Subject: tools lib traceevent: Rename pevent_data_ APIs 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_data_lat_fmt, pevent_data_type, pevent_data_event_from_type, pevent_data_pid, pevent_data_preempt_count, pevent_data_flags, pevent_data_comm_from_pid, pevent_data_pid_from_comm, pevent_cmdline_pid 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/20180808180702.678020020@goodmis.org Signed-off-by: Steven Rostedt Signed-off-by: Arnaldo Carvalho de Melo --- tools/lib/traceevent/event-parse.c | 44 ++++++++++++++++++------------------- tools/lib/traceevent/event-parse.h | 22 +++++++++---------- tools/lib/traceevent/parse-filter.c | 6 ++--- 3 files changed, 36 insertions(+), 36 deletions(-) (limited to 'tools') diff --git a/tools/lib/traceevent/event-parse.c b/tools/lib/traceevent/event-parse.c index 0de470c07be9..4f924bf42b92 100644 --- a/tools/lib/traceevent/event-parse.c +++ b/tools/lib/traceevent/event-parse.c @@ -5140,7 +5140,7 @@ out_failed: } /** - * pevent_data_lat_fmt - parse the data for the latency format + * tep_data_lat_fmt - parse the data for the latency format * @pevent: a handle to the pevent * @s: the trace_seq to write to * @record: the record to read from @@ -5149,8 +5149,8 @@ out_failed: * need rescheduling, in hard/soft interrupt, preempt count * and lock depth) and places it into the trace_seq. */ -void pevent_data_lat_fmt(struct tep_handle *pevent, - struct trace_seq *s, struct tep_record *record) +void tep_data_lat_fmt(struct tep_handle *pevent, + struct trace_seq *s, struct tep_record *record) { static int check_lock_depth = 1;
