Subject: [for-next][PATCH 07/20] tracing: Move struct filter_pred into trace_events_filter.c

From: "Steven Rostedt (Google)" <rostedt@...dmis.org>

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.
