From f3acd8869b9badcfd91cf50a2b6242be7b9368e2 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 2 Aug 2018 15:11:58 -0300 Subject: [PATCH] perf trace: Use perf_evsel__sc_tp_{uint,ptr} for "id"/"args" handling syscalls:* events Now it looks just about the same as for the trace__sys_{enter,exit}.
