From e0af43d2486fc50208076cfd93af55615fd4adfd Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Sat, 1 Dec 2012 21:18:20 +0100 Subject: [PATCH] perf hists: Marking dummy hists entries It does not make sense to make some computation (ratio, wdiff), when the hist_entry is 'dummy' - added via hists__link. Adding dummy field to struct hist_entry which indicates that it was added by hists__link and avoiding some of the processing for such entries.
