From d549c7690190d9739005e19604faad6da4b802ac Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Sun, 27 Dec 2009 21:37:02 -0200 Subject: perf session: Remove sample_type_check from event_ops MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is really something tools need to do before asking for the events to be processed, leaving perf_session__process_events to do just that, process events. Also add a msg parameter to perf_session__has_traces() so that the right message can be printed, fixing a regression added by me in the previous cset (right timechart message) and also fixing 'perf kmem', that was not asking if 'perf kmem record' was ran.
