[PATCH] tracing: synth events: increase max fields count

From: Artem Bityutskiy
Date: Wed Sep 01 2021 - 09:55:18 EST


From: Artem Bityutskiy <artem.bityutskiy@xxxxxxxxxxxxxxx>

Sometimes it is useful to construct larger synthetic trace events. Increase
'SYNTH_FIELDS_MAX' (maximum number of fields in a synthetic event) from 32 to
64.
