From 2e5e5f876143b147b98d0c0854b5fc577412b05b Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 3 Aug 2015 17:12:29 -0300 Subject: [PATCH] perf trace: Do not show syscall tracepoint filter in the --no-syscalls case We were accessing trace->syscalls.events members even when that struct wasn't initialized, i.e. --no-syscalls was specified on the command line, fix it to show that, still in debug mode, when we have an event qualifier list, i.e. when we actually are doing subset syscall tracing.
