From b2f974d6af9accfec11e69cc76d2ab9f0c7359e0 Mon Sep 17 00:00:00 2001 From: Cody P Schafer Date: Wed, 23 Oct 2013 11:49:57 -0700 Subject: [PATCH] tracing: Open tracer when ftrace_dump_on_oops is used With ftrace_dump_on_oops, we previously did not open the tracer in question, sometimes causing the trace output to be useless. For example, the function_graph tracer with tracing_thresh set dumped via ftrace_dump_on_oops would show a series of '}' indented at different levels, but no function names. call trace->open() (and do a few other fixups copied from the normal dump path) to make the output more intelligible.
