From 0cae013cf4450ea0ecb62241a2f3e7565db09f93 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Wed, 1 Oct 2014 18:00:28 +0200 Subject: [PATCH] perf kvm stat live: Use perf_evlist__add_pollfd return fd position With the interface changed in following commit: 2171a9256862 tools lib fd array: Allow associating an integer cookie with each entry the perf_evlist__add_pollfd function now returns the fd position in the pollfd array. Hence we no longer need to count the fd position, because we get it as the return value.
