From cac21425578abddc4e9f529845832a57ba27ce0f Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Mon, 12 Nov 2012 18:34:00 +0100 Subject: [PATCH] perf tools: Fix attributes for '{}' defined event groups Fixing events attributes for groups defined via '{}'. Currently 'enable_on_exec' attribute in record command and both 'disabled ' and 'enable_on_exec' attributes in stat command are set based on the 'group' option. This eliminates proper setup for '{}' defined groups as they don't set 'group' option. Making above attributes values based on the 'evsel->leader' as this is common to both group definition. Moving perf_evlist__set_leader call within builtin-record ahead perf_evlist__config_attrs call, because the latter needs possible group leader links in place.
