From 610e1e4ff0431b3a86a0ebfcdb47828b8e082329 Mon Sep 17 00:00:00 2001 From: "Tzvetomir Stoyanov (VMware)" Date: Wed, 8 Aug 2018 14:03:05 -0400 Subject: [PATCH] tools lib traceevent: Rename pevent_find_* 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_find_function, pevent_find_function_address, pevent_find_event_by_name, pevent_find_event_by_record 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/20180808180702.966965051@goodmis.org Signed-off-by: Steven Rostedt Signed-off-by: Arnaldo Carvalho de Melo --- tools/lib/traceevent/event-parse.c | 24 ++++++++++++------------ tools/lib/traceevent/event-parse.h | 8 ++++---- tools/lib/traceevent/parse-filter.c | 10 +++++----- tools/lib/traceevent/plugin_function.c | 4 ++-- tools/lib/traceevent/plugin_kmem.c | 4 ++-- 5 files changed, 25 insertions(+), 25 deletions(-) diff --git a/tools/lib/traceevent/event-parse.c b/tools/lib/traceevent/event-parse.c index 652b8ef6f4c7..53d866434478 100644 --- a/tools/lib/traceevent/event-parse.c +++ b/tools/lib/traceevent/event-parse.c @@ -503,7 +503,7 @@ find_func(struct tep_handle *pevent, unsigned long long addr) } /** - * pevent_find_function - find a function by a given address + * tep_find_function - find a function by a given address * @pevent: handle for the pevent * @addr: the address to find the function with * @@ -511,7 +511,7 @@ find_func(struct tep_handle *pevent, unsigned long long addr) * address.
