From 9d9cad763ca79dd3697e9f2d1df648e37496582b Mon Sep 17 00:00:00 2001 From: Kan Liang Date: Wed, 17 Jun 2015 09:51:11 -0400 Subject: perf tools: Configurable per thread proc map processing time out The time out to limit the individual proc map processing was hard code to 500ms. This patch introduce a new option --proc-map-timeout to make the time limit configurable.
