From 12c142781ec076fad617e7cd9f83c8618d909619 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 4 Jan 2012 12:27:03 -0200 Subject: [PATCH] perf hists: Stop using 'self' for struct hist_entry Stop using this python/OOP convention, doesn't really helps. Will do more from time to time till we get it cleaned up in all of /perf.
