From 712a4b6049724278121d56aba683151d86c8c35a Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 17 Feb 2011 12:18:42 -0200 Subject: [PATCH] perf record: Delay setting the header writing atexit call While testing the --filter option I noticed that we were writing lots of unneeded stuff to the perf.data header when the filter ioctl fails, so move the atexit(atexit_header) call to after we create the counters successfully.
