Commit-ID: 007d66a0bd43d886eb3e4aceaf1a96b8743ccaff Gitweb: http://git.kernel.org/tip/007d66a0bd43d886eb3e4aceaf1a96b8743ccaff Author: Milian Wolff <milian.wolff@xxxxxxxx> AuthorDate: Wed, 5 Aug 2015 16:52:23 -0300 Committer: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx> CommitDate: Wed, 5 Aug 2015 16:52:23 -0300 perf trace: Write to stderr by default 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.
