From: Milian Wolff <milian.wo...@kdab.com> Without this patch, it is cumbersome to read the trace output but ignoring the normal, potentially verbose, output of the debuggee. One common example is doing something like the following:
perf trace -s find /tmp > /dev/null Without this patch, the trace summary will be lost. Now, it will still be printed at the end. This behavior is also applied by strace.
