In linux kernel since version 5.1 (release Date: 2019-05-05)  
Synthetic events are user-defined trace events that can be
used to combine data from other trace events or in fact any
data source. Synthetic events can be generated indirectly
via the trace() action of histogram triggers or directly
by way of an in-kernel API.

See Documentation/trace/events.rst or Documentation/trace/histogram.rst for details and examples.

If in doubt, say N.
