From c45a81682d6d15b7ec82ed90c34a537de66dea55 Mon Sep 17 00:00:00 2001 From: Michael Roth Date: Sun, 2 Oct 2011 08:44:37 -0500 Subject: hmp: re-enable trace-file command Commit 31965ae27bc11e90674be12584bb201b83df5aef reverted a previous renaming of CONFIG_SIMPLE_TRACE->CONFIG_TRACE_SIMPLE in a couple spots, leading to trace-file currently being unavailable.
