From 246d4ce8107ea16521384c8b2a8fcff354ef2b7c Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 11 Nov 2011 23:10:26 -0200 Subject: perf session: Remove superfluous callchain_cursor member Since we have it in evsel->hists.callchain_cursor, remove it from perf_session. One more step in disentangling several places from requiring a perf_session pointer.

Next steps will remove the 'session' pointer, that in most cases is not needed. Then we can rename perf_event_ops to 'perf_tool' that better describes this class hierarchy.

For perf-report it means comm list. Then perf-annotate, perf-report and perf-script use -c for cpu list. Fix annotate, report and script to use -C for cpu list to be consistent with top, stat and record.
