From e02092b9a922f17e951b2df5f12f4aafe7383a21 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 19 Apr 2016 12:12:49 -0300 Subject: perf symbols: Allow loading kallsyms without considering kcore files Before the support for using /proc/kcore was introduced, the kallsyms routines used /proc/modules and the first 'perf test' entry expected finding maps for each module in the system, which is not the case with the kcore code. Provide a way to ignore kcore files so that the test can have its expectations met. Improving the test to cover kcore files as well needs to be done.
