From 806fb63007447622dd61d9767b4403919737e120 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 29 Nov 2011 08:05:52 -0200 Subject: perf evlist: Always do automatic allocation of pollfd and mmap structures At first tools were required to do that, but while writing the python bindings to simplify the API I made them auto-allocate when needed. This just makes record, stat and top use that auto allocation, simplifying them a bit.
