[PATCH 2/6] perf session: Ditch register_perf_file_handler
From: Arnaldo Carvalho de Melo
Date: Sun Dec 13 2009 - 16:51:26 EST
From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>
Pass the event_ops to perf_session__process_events instead.
Also move the event_ops definition to session.h, starting to move things
around to their right place, trimming the many unneeded headers we have.
