From 8dd2a1317eba2c207632dcb19adb7cb746861652 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Mon, 7 Sep 2015 10:38:06 +0200 Subject: perf evsel: Propagate error info from tp_format Propagate error info from tp_format via ERR_PTR to get it all the way down to the parse-event.c tracepoint adding routines. Following functions now return pointer with encoded error: - tp_format - trace_event__tp_format - perf_evsel__newtp_idx - perf_evsel__newtp This affects several other places in perf, that cannot use pointer check anymore, but must utilize the err.h interface, when getting error information from above functions list.
