From 6782206b5dfece4c51f587b3ca1540a4027f87dd Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 12 Apr 2012 14:21:01 +0200 Subject: [PATCH] perf session: Skip event correctly for unknown id/machine In case the perf_session__process_event function fails, we estimate the next event offset. This is not necessary for sample event failing on unknown ID or machine. In such case we know proper size of the event, so we dont need to guess. Also failure statistics are updated correctly so we don't miss any information. Forcing perf_session__process_event to return 0 in case of unknown ID or machine.
