From d02f40e81e003be6ddba5c176f2e40ea290c3729 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 24 Jun 2006 14:32:18 -0700 Subject: [PATCH] Enable minimal per-device resume tracing This is the minimal resume trace code to find which device resume (if any) results in problems. Usually, you'd use the information this generates as a starting point to adding more fine-grained trace event points.
