[PATCH 3/4] tracing: Move struct filter_pred into trace_events_filter.c

From: Steven Rostedt
Date: Tue Aug 23 2022 - 17:51:28 EST


From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx>

The structure filter_pred and the typedef of the function used are only
referenced by trace_events_filter.c. There's no reason to have it in an
external header file. Move them into the only file they are used in.
