parentperf tools: Fix modifier to be applied on correct events (diff)
perf diff: Fix to work with new hists design
The perf diff command is broken since: perf hists: Threaded addition and sorting of entries commit 1980c2ebd7020d82c024b8c4046849b38e78e7da Several places were broken: - hists data need to be collected into opened sessions instead of into events - session's hists data need to be initialized properly when the session is created - hist_entry__pcnt_snprintf: the percentage and displacement buffer preparation must not use 'ret' because it's used as a pointer to the final buffer Signed-off-by: Jiri Olsa <jolsa@redhat.com> Cc: Corey Ashford <cjashfor@linux.vnet.ibm.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/20120322133726.GB1601@m.brq.redhat.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
