[PATCH v3 1/5] perf tools: Add all matching dynamic sort keys for field name

Show all headers | View raw

When a perf.data file has multiple events, it's likely to be similar
(tracepoint) events.  In that case, they might have same field name so
add all of them to sort keys instead of bailing out.

In addition, it contains a trivial whitespace fix at callsite of
add_all_dynamic_fields().
