From aae59fab978e143f24d22e52f075c4be3ee4e628 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 31 Mar 2015 09:53:50 -0300 Subject: [PATCH] perf session: Always initialize ordered_events Even when it is not used to actually reorder events, some of its fields are used, like session->ordered_events->tool, to shorten function signatures where tool, for instance, was being passed, as the tool is needed for the ordered_events code, we need it there and might as well use it for other perf_session needs. This fixes a problem where 'perf script' had some condition that made session->ordered_events not to be initialized even with its script->tool ordered_events related flags asking for it to be, which looks like another bug and needs to be investigated further. Always initializing session->ordered_events at least leaves the current assumptions in place, so do it now.
