From fe176085a4d45fb241c04beea872ecbb8bef6a55 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 19 May 2016 11:34:06 -0300 Subject: perf tools: Fix usage of max_stack sysctl We cannot limit processing stacks from the current value of the sysctl, as we may be processing perf.data files, possibly from other machines. Instead use the old PERF_MAX_STACK_DEPTH, the sysctl default, that can be overriden using --max-stack or equivalent.
