From 301a0b020210360c6e441c7765521248bc87d58e Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Sun, 13 Dec 2009 19:50:25 -0200 Subject: [PATCH] perf session: Ditch register_perf_file_handler MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
