From 84530920de3c6ccb92c6661da784f6cdb66d3304 Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Wed, 6 Jan 2016 19:50:01 +0100 Subject: perf pmu: fix alias->snapshot missing initialization bug This patch fixes a bug in __perf_pmu__new_alias() whereby the alias->snapshot field was not initialized to false. This led to random alias->snapshot value for an alias and was breaking some measurements such as: $ perf stat -a -e uncore_imc/data_reads/ -I 1000 sleep 100 Because the event ended up being treated as snapshot mode, when it is not.
