From d04b35f8085f0d4c5c874515b8f65e7664357148 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 11 Nov 2011 22:17:32 -0200 Subject: perf symbols: Add nr_events to symbol_conf Since symbol__alloc_hists need it, to avoid passing it around in many functions have it in the symbol_conf struct.
