    Subject[PATCH 09/15] perf tools: Continue processing header on unknown features
    Date
    From: Robert Richter <robert.richter@amd.com>

    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.
