From d0d3913895e5b50623bd4dafd876e41c1169031d Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 14 Aug 2012 10:57:03 +0900 Subject: [PATCH] perf script: Fix a NULL pointer dereference If 'perf script --gen-script' was called with a perf.data which contains no tracepoint event, it'd segfault due to NULL pevent pointer. Fix it.
