From f7a8a1336416883dc0ccd96c17c604e34de61c25 Mon Sep 17 00:00:00 2001 From: Robert Richter Date: Wed, 7 Dec 2011 10:02:51 +0100 Subject: [PATCH] perf tools: Continue processing header on unknown features A feature may be unknown if perf.data is created and parsed on different perf tool versions. This should not stop the header to be processed, instead continue processing it.
